card as promptly as possible in the enclosed postage-prepaid

				 BY ORDER OF THE BOARD OF DIRECTORS

				    /s/ Benedict C. K. Choy
					Secretary

			    SUPTERTEX, INC.
			   PROXY STATEMENT

	    SOLICITATION  OF PROXY, REVOCABILITY AND VOTING

General

 The enclosed Proxy is solicited on behalf of the Board of
Directors of Supertex, Inc., a California corporation (the
"Company"), for use at the 1999 Annual Meeting of Shareholders
to be held on August 6, 1999 at 10:00 a.m., local time, or at
any adjournment thereof, for the purposes set forth herein and
in the accompanying Notice of Annual Meeting of Shareholders.

 Only shareholders of record at the close of business on June 14,
1999 (the "Record Date") are entitled to notice of and to vote
at the meeting.  At the Record Date, 12,074,668 shares of the
Company's Common Stock, no par value, were issued and
outstanding.

 The Annual Meeting will be held at the principal offices of the
Company located at 1235 Bordeaux Drive, Sunnyvale, California
94089.  The Company's telephone number at that address is (408)
744-0100.

 These proxy solicitation materials were mailed on or about July
2, 1999 to all shareholders entitled to vote at the meeting.

Revocability of Proxies

 Any proxy given pursuant to this solicitation may be revoked by
the person giving it at any time before its use (i) by
delivering to the Secretary of the Company a written notice of
revocation or a duly executed proxy bearing a later date or (ii)
by attending the meeting and voting in person.

Voting and Solicitation

 Every shareholder voting at the election of directors may
cumulate such shareholder's votes and give one candidate a
number of votes equal to the number of directors to be elected
multiplied by the number of votes to which the shareholder's
shares are entitled, or distribute the shareholder's votes on
the same principle among as many candidates as the shareholder
thinks fit, provided that votes cannot be cast for a greater
number of candidates than the number of directors to be elected.
However, no shareholder shall be entitled to cumulate votes
unless the candidate's name has been placed in nomination prior
to the voting and the shareholder, or any other shareholder, has
given notice at the meeting prior to the voting of the intention
to cumulate the shareholder's votes.  On all other matters, each
share has one vote.  An automated system administered by the
Company's transfer agent, Registrar and Transfer Company,
tabulates the votes.

Quorum; Abstentions; Broker Non-Votes

 The required quorum for the transaction of business at the
Annual Meeting is a majority of the shares of Common Stock
issued and outstanding on the Record Date.  Shares that are
voted "FOR", "AGAINST" or "WITHHELD FROM" a matter are treated
as being present at the meeting for purposes of establishing a
quorum and are also treated as shares "represented and voting"
at the Annual Meeting (the "Votes Cast") with respect to such
matter.

 While there is no definitive statutory or case law authority in
California as to the proper treatment of abstentions, the
Company believes that abstentions should be counted for purposes
of determining the presence or absence of a quorum for the
transaction of business, but should not be counted as Votes Cast
with respect to a proposal, since the shareholder has expressly
declined to vote on such proposal.  Similarly, broker non-votes
will be counted for purposes of determining the presence or
absence of a quorum for the transaction of business, but will
not be counted for purposes of determining the number of Votes
Cast with respect to the proposal on which the broker has
expressly not voted.

<PAGE>

 Accordingly, abstentions and broker non-votes will not affect
the outcome of the voting on a proposal that requires a majority
of the Votes Cast (such as the approval of a plan).  However,
with respect to a proposal that requires a majority of the
outstanding shares, (such as an amendment to the articles of
incorporation), an abstention or broker non-vote has the same
effect as a vote against the proposal.

 The Company will bear the entire cost of preparing, assembling,
printing, and mailing this Proxy Statement.  In addition, the
Company may reimburse brokerage firms and other persons
representing beneficial owners of shares for their expenses in
forwarding solicitation materials to such beneficial owners.
Proxies may also be solicited personally or by telephone or by
fax by certain of the Company's directors, officers, and regular
employees - such persons will not receive additional
compensation for such solicitation.

Deadline for Receipt of Shareholder Proposals

 Proposals of security holders of the Company which are intended
to be presented by such shareholders at the Company's Annual
Meeting for fiscal 2000 must be received by the Company no later
than February 24, 2000 in order that they may be included in the
proxy statement and form of proxy relating to that meeting.


		PROPOSAL 1:  ELECTION OF DIRECTORS

Nominees

 A board of five (5) directors is to be elected at the meeting.
Currently, the board consists of five (5) directors.  Unless
otherwise instructed, the proxy holders will vote the proxies
received by them for the Company's five nominees named below.
The five nominees receiving the highest number of affirmative
votes of the shares entitled to be voted will be elected as
directors of the Company.  In the event that any nominee of the
Company declines or is unable to serve as a director at the time
of the Annual Meeting, the proxies will be voted for any nominee
who shall be designated by the present Board of Directors to
fill the vacancy.  It is not expected that any nominee will
decline or will be unable to serve as a director.  In the event
that additional persons are nominated for election as directors,
the proxy holders intend to vote all proxies received by them in
such a manner as will ensure the election of as many of the
nominees listed below as possible, and, in such event, the
specific nominees to be voted for will be determined by the
proxy holders.  The term of office of each person elected as a
director will continue until the next Annual Meeting of
Shareholders until such person's successor has been elected
and qualified.  The names of the nominees and certain
information about them are set forth below.

       Report of the Compensation Committee and Executive
	Stock Option Committee of the Board of Directors

 The Compensation Committee of the Board of Directors is
generally responsible for reviewing compensation and benefits of
executive officers of the Company; except for the stock options
to executive officers and directors of the Company, for which
the Executive Stock Option Committee is responsible.

 The Company applies a consistent philosophy of compensation
for all employees, including its executive officers.  This
philosophy is based on the premise that the achievements of the
Company result from the coordinated efforts of all individuals
working toward common objectives.  The Company strives to
achieve those objectives through teamwork that is focused on
meeting the defined expectations of customers and shareholders.

 Compensation Philosophy.  The goals of these committees are to
align executive compensation with business objectives and
performance, and to enable the Company to attract, retain and
reward executive officers who contribute to the long-term
success of the Company.  The Company's compensation program for
the chief executive officer and other executive officers is
based on the same four principles applicable to compensation
decisions for all employees of the Company:

* The Company pays competitively.  The Company is committed to
  providing a compensation program that helps attract and retain
  the best people in the industry.  To ensure that pay is
  competitive, the Company reviews the compensation practices of
  other companies of similar size and sales volume within the
  semiconductor industry, most of which are included in the Nasdaq
  Electronic Component Index.

* The Company pays for relative sustained performance.  Officers
  are rewarded based upon corporate performance, product line
  performance and individual performance.  Corporate performance
  and product line performance are evaluated by reviewing the
  extent to which strategic and business plan goals are met,
  including such factors as operating profit, performance relative
  to competitors and timely new product introductions.  Individual
  performance is evaluated by measuring organization progress
  against set objectives.

* The Company strives for fairness in the administration of
  compensation.  The Company strives to achieve a balance with
  respect to compensation paid to the executives within the
  Company and in comparable companies.  The Company also believes
  that the contributions of each member of the executive staff are

<PAGE>

  vital to the success of the Company.  As such, the Compensation
  Committee's current policy is that the CEO's base compensation
  does not have any bearing on the base compensation of the other
  officers.  Similarly, any employee may receive a base
  compensation higher than his/her supervisor due to the
  particular higher technical skills required in the subordinate
  position.

* The Company believes that employees should understand the
  performance evaluation and compensation administration process.
  At the beginning of each focal review period in July, annual
  objectives for the Company are set for each officer.  The CEO
  gives ongoing feedback on performance to each officer.  Within
  90 days after the end of the fiscal year, the committees
  evaluate the accomplishments of the key objectives, which
  affects decisions on merit increases and stock option grants.

Compensation Components.  The Company's compensation program,
which consists of cash- and equity-based compensation, allows
the Company to attract and retain highly skilled officers,
provide useful products and services to customers, enhance
shareholder value, motivate technological innovation and
adequately reward its executive officers and other employees.
These components are:

Cash-Based Compensation:

Salary.  The Compensation Committee sets base salary for the
chief executive officer and all other officers by reviewing the
compensation levels for competitive positions in the market.
Based on comparative data, the chief executive officer and all
other officers were compensated within the low-to-middle salary
range levels during fiscal 1999.  The chief executive officer
and all other officers of the Company largely met their
individual goals and the Company's overall performance set for
them in fiscal 1999.

Profit-Sharing Bonus.  The Company has a semiannual
profit-sharing plan under which it distributes to all employees,
including the chief executive officer and all other officers,
ten percent of its operating profits before taxes and other
adjustments.  The Company believes that all employees share the
responsibility of achieving profits.  Accordingly, it awards a
bonus to all employees based on a formula which includes
employment grade level, seniority with the Company, and employee
performance including attendance.  As of June 14, 1999, the
Company has made twenty two consecutive semiannual profit-
sharing distributions.

Equity-Based Compensation:

Stock Option Grants.  Stock options provide additional
incentives to the chief executive officer and all other
officers, directors,  and certain management and
technical employees to work to maximize stockholder value.  The
options vest over a defined period to encourage such employees
to continue in the employ of the Company.  In line with its
compensation philosophy, the Company grants stock options
commensurate with the employee's potential contribution to the
Company, measured by his qualifications and previous work
performance.  Stock options were granted to various officers,
management or technical employees in fiscal year 1999 for
performance and promotions of existing employees, and as a part
of the employment compensation package for new employees.

                     -Respectfully submitted by the
                      members of the Compensation Committee

				    Yunni Pao       Henry C. Pao
				    Benedict C. K. Choy

<PAGE>

Compensation of Directors

Cash Compensation.  The Company currently pays cash
compensation to its outside Directors for serving on the Board
or committees of the Board in an amount of $500 for each Board
meeting attended in person not via telephone.  The Company also
reimburses all outside Directors for travel and other necessary
out-of-pocket expenses incurred in the performance of their
services as directors.

Certain Transactions:  Lease with Company Director

 The manufacturing facility of the Company is leased from
Fortuna Realty Co., a corporation owned by Supertex Director,
Yunni Pao.  The five-year operating lease agreement with Fortuna
Realty expires in February 2001.  The total rental expenses paid
to the company director were, $375,000, $362,000, and $352,000
in fiscal 1999, 1998, and 1997 respectively.  The Company believes
that the lease with Fortuna Realty Co. is at prevailing market rates.

required by SEC rules to furnish the Company with copies of all
Section 16(a) forms they file.

 Based solely on its review of the copies of such forms received
by it, or written representations from certain reporting persons
that no Forms 5 were required for such persons, the Company
believes that, during the fiscal year ended March 27, 1999, all
Section 16(a) filing requirements applicable to its officers,
directors, and 10% shareholders were satisfied.

 In June 1998, William Numann, the Company's Vice President, DMOS Products,
was given the opportunity to exchange his older higher priced incentive
stock options for new incentive stock options at the then current market price
of $10.75 per share in return for changing the vesting start date of the option
to one year after the original vesting date for the surrendered option.
The Board believes that it is in the best interest of the Company and the
shareholders of the Company to highly motivate William Numann, he being a new
officer of the Company at the time and to make a special exchange offer that is
not available to the rest of the officers of the Company.

    PROPOSAL 2: RESERVATION OF ADITIONAL 900,000
                SHARES FOR ISSUANCE UNDER THE 1991
                STOCK OPTION PLAN AND THE ADOPTION
                OF AN ANNUAL OPTION GRANT LIMIT

 At the Annual Meeting, Shareholders are being asked to approve
two amendments to the Company's Amended and Restated 1991 Stock Option
Plan ( the "1991" Plan).  The 1991 Plan provides a means to attract and
retain officers and key employees and promote the success of the Company.

Proposed Amendments to the Plan

 Subject to approval by a majority of the Shareholders, the Board of Directors
has approved two amendments to the 1991 Plan: (i) increasing in the number
of shares of Common Stock of the Company ("Common Stock") reserved under the
1991 Plan by 900,000 shares, from 1,925,715 to 2,825,715 shares, and (ii)
setting an annual limit as to the number of shares subject to options that
may be granted to any individual under the 1991 Plan (the "Annual Limit").

 As of June 14, 1999, the Company had a limited number of shares available for
grant under the 1991 Plan, which is the Company's primary mechanism for
providing equity incentives to the Company's employees; thus, the Company
cannot fulfill its compensation objectives.  Equity incentives have
continually been a significant component of compensation for the Company's
employees.  By linking key employees' compensation to corporate performance,
the employees' reward is directly related to the Company's success.  The
Company believes the use of equity incentives increases employee motivation
to improve Shareholder value.  In addition, the market for employees in
technology companies, such as the Company, is extremely competitive.
Consequently, the Board of Directors believes additional shares must be
reserved under the Plan to enable the Company to attract and retain key
employees through the granting of options under the 1991 Plan.

 Any stock options granted under the 1991 Plan after the date of the
shareholder approval of the Annual Limit will be exempt from the $1,000,000
compensation limitation of section 162(m) of the Internal Revenue Code of
1986, as amended (the "Code").  Consequently, the Company will be able to
fully deduct any compensation expense (for tax purposes) attributable to
option exercises relating to such stock option grants that otherwise would not
be deductible under Section162(m) of the Code.  Therefore, the Board of
Directors believes that adoption of the Annual Limit is in the best interest
of the Company.

Summary Description of the 1991 Plan

 The following description of the 1991 Plan is qualified in its entirety by
reference to the full text of the 1991 Plan, a copy of which may be obtained by
Shareholders of the Company upon written request directed to the Company's
Secretary at the address listed on the first page of this Proxy Statement.

Purpose

 The purposes of the 1991 Plan are to attract and retain the best
available personnel for positions of substantial responsibility,
to provide additional incentive to employees and consultants, and to
promote the success of the Company's business. Options granted under the
1991 Plan may be either "incentive stock options", as defined in Section
422 of the Internal Revenue Code of 1986, as amended (the "Code"), or
nonstatutory stock options.

Administration

 The 1991 Plan is administered by the Board of Directors, or by a
committee designated by the Board of Directors which committee shall
be constituted to satisfy applicable laws.  The interpretation and
construction of any provision of the 1991 Plan by the Board of Directors
or its committee shall be final and conclusive.

<PAGE>

Eligibility

 The 1991 Plan provides for granting nonstatutory stock options to
employees and consultants, and incentive stock options only to employees.
The Administrator in its discretion, selects the employees and consultants
to whom options may be granted, the time or times at which such options
shall be granted, and the exercise price and number of shares subject to
each such grant.

Limitations

 Section 162(m) of the Code places limits on the deductibility for federal
income tax purposes of compensation paid to certain executive officers of the
Company.  In order to preserve the Company's ability to deduct the
compensation income associated with options granted to such persons, the 1991
Plan provides that no employee may be granted, in any fiscal year of the
Company, options to purchase more than 125,000 shares of Common Stock.
Notwithstanding this limit, however, in connection with such individual's
initial employment with the Company, he or she may be granted options to
purchase up to an additional 125,000 shares of Common Stock.


Term and Conditions of Options

 Each option is evidenced by a written stock option agreement between
the Company and the optionee and is subject to the terms and conditions
listed below:

      (a)  Exercise of Options.  The Administrator determines when options
           become exercisable, and may in its discretion, accelerate the vesting
           of any outstanding option.  The means of payment for shares issued
           upon exercise of an option is specified in each option agreement.
           An option is exercised by giving written notice of exercise to the
           Company and tendering full payment of the purchase price to the
           Company.  Payment for shares issued upon exercise of an option may
           be by cash, check, or surrender of other shares of the Company's
           Common Stock which have been owned by the optionee for more than six
           months and have a fair market value equal to the aggregate exercise
           price of the shares as to which the option will be exercised on the
           date of surrender.


      (b)  Option Price.  The exercise price of options granted under the 1991
           Plan is the fair market value of the Company's Common Stock as
           determined by the Board of Directors or its appointed committee at
           time the options are granted.  The exercise price of an incentive
           stock option may not be less than 100% of the fair market value
           of the Common Stock on the date such option is granted; provided,
           however, the exercise price of an incentive stock option granted
           to a 10% shareholder may not be less than 110% of the fair market
           value of the Common Stock on the date such option is granted.
           The 1991 Plan provides that, because the Company's Common Stock is
           currently traded on The Nasdaq Stock Market, the fair market value
           per share shall be the closing price as quoted on such system on
           the last market trading day prior to the day of the option.


      (c)  Termination of Employment or Consulting Relationship.  If an
           optionee's employment or consulting relationship with the
           Company terminates for any reason (including death or disability),
           then all options held by the optionee under the 1991 Plan expire on
           the earlier of (i) the date set forth in his or her notice of grant
           or (ii) the expiration date of such option.  The 1991 Plan and the
           option agreement may provide for a longer period of time for the
           option to be exercised after the optionee's death or disability
           than for other terminations.  To the extent the option is exercisable
           at the time of such termination, the optionee (or the optionee's
           estate or the person who acquires the right to exercise the option
           by bequest or inheritance) may exercise all or part of his or her
           option at any time before termination.


     (d)   Non-transferability of Options.  Unless otherwise determined by the
           Administrator, an option is not transferable other than by will or by
           the laws of descent or distribution and may be exercised, during the
           lifetime of the optionee, only by the optionee.

     (e)   Terms of Options.  The term of each option shall be ten (10) years
           from the date of grant; provided that in the case of an incentive
           stock option granted to a 10% shareholder,

<PAGE>

           the term of the option may be no more than five (5) years from the
           date of grant.  No option may be exercised after the expiration of
           its term.

     (f)   Other Provisions.  The stock option agreement may contain other
           terms, provisions and conditions not inconsistent with the 1991
           Plan as may be determined by the Administrator.

Adjustments Upon Changes in Capitalization

 In the event that the stock of the Company changes by reason of any stock
split, reverse stock split, stock dividend, combination, reclassification or
other similar change in the capital structure of the Company effected
without the receipt of consideration, appropriate adjustments shall be made
in the number and class of shares of stock subject to the 1991 Plan, the number
and class of shares of stock subject to any option outstanding under the 1991
Plan, and the exercise price of any such outstanding option.

 In the event of a liquidation or dissolution, any unexercised options will
terminate.  The Administrator may, in its sole discretion, provide that each
optionee shall have the right to exercise all of the optionee's options,
including those not otherwise exercisable.

 In connection with any merger, consolidation, acquisition of assets or like
occurrence involving the Company, each outstanding option shall be assumed or
an equivalent option substituted by the successor corporation.  If the
successor corporation refuses to assume the options or to substitute
substantially equivalent options, the Administrator shall have the discretion
to allow the optionee to exercise the option to the extent the option would
have been exercisable 180 days after the effective date of the merger or sale
of assets.  In such event, the Administrator shall notify the optionee that
the option is fully exercisable for fifteen (15) days from the date of such
notice and that the option terminates upon expiration of such period.


Amendment and Termination of the 1991 Plan

  The Board of Directors may at any time amend, alter, suspend or terminate
the 1991 Plan; but, no amendment or termination shall be made that would
impair the rights of any participant under any grant theretofore made, without
the written consent of the optionee.  In addition, the Company shall obtain
shareholder approval of any amendment to the 1991 Plan in such a manner and
to the extent necessary and desirable to comply with applicable law or
regulation.  Unless terminated earlier, the 1991 Plan shall terminate ten
years from the date of its approval by the shareholders or the Board of the
Company, whichever is earlier.

Federal Income Tax Information

 An optionee who is granted an incentive stock option will not
recognize income either at the time the option is granted or upon
its exercise, although the exercise may subject the optionee
to the alternative minimum tax.  Upon a sale or exchange of
the shares more than two years after the grant of the option
and one year after its exercise, any gain or loss will be
treated as long-term capital gain or loss.  Net capital gains on
shares held more than 12 months may be taxed at a maximum federal
rate of 20%.  Capital losses are allowed in full against capital
gains and up to $3,000 against other income.  If these holding
periods are not satisfied, the optionee will recognize ordinary
income at the time of the sale or exchange equal to the difference
between the exercise price and the lower of (i) the fair market
value of the shares on the date of exercise or (ii) the sale price
of the shares.  A different rule for measuring ordinary income
upon such a premature disposition may apply if the optionee is
also an officer, director, or 10% shareholder of the Company.

 Any gain or loss recognized on such premature disposition of the
shares in excess of the amount treated as ordinary income will
be characterized as long-term or short-term capital gain or loss,
depending on the holding period.  A different rule for measuring
ordinary income upon such a premature disposition may apply if the
optionee is also an officer, director, or 10% shareholder of the
Company.  Unless limited by Section 162(m) of the Code, the
Company will be entitled to a deduction in the same amount as the
ordinary income recognized by the optionee at the time of such
disposition.

<PAGE>

 Options that do not qualify as incentive stock options are
referred to as nonstatutory options.  An optionee will not recognize
income at the time a nonstatutory option is granted.  However, upon
its exercise, the optionee will recognize ordinary income generally
measured as the excess of the then fair market value of the shares
over the exercise price.  Any ordinary income recognized in connection
with the exercise of a nonstatutory option by an optionee who is also
an employee of the Company will be subject to tax withholding by the
Company.  Unless limited by Section 162(m) of the Code, the Company
will be entitled to a tax deduction in the same amount as the ordinary
income recognized by the optionee upon exercise of a nonstatutory stock
option.

 Upon resale of the shares by the optionee, any difference between
the sale price and the optionee's purchase price, to the extent not
recognized as ordinary income as described above, will be treated
as long-term or short-term capital gain or loss, depending on the
holding period.  Net capital gains on shares held more than 12 months
may be taxed at a maximum federal rate of 20%.  Capital losses are
allowed in full against capital gains and up to $3,000 against other
income.

 The foregoing is only a summary of the effect of federal income
taxation upon the optionee and the Company with respect to the grant
and exercise of the options under the 1991 Plan.  It does not purport
to be complete, and it does not discuss the tax consequences of the
optionee's death or the income tax laws of any municipality, state
or foreign country in which an optionee may reside.

 Approval of the reservation of an additional 900,000 shares for
issuance under the Company's 1991 Stock Option Plan and the adoption
of an annual option grant limit requires the affirmative vote of the
holders of a majority of shares present at the Annual Meeting in person
or by proxy and entitled to vote as of the Record Date.

 The Board of Directors recommends a vote FOR the approval of the
 reservation of an additional 900,000 shares for issuance under the
 Company's 1991 Stock Option Plan and the adoption of an annual
 option grant limit.
