                            PROXY STATEMENT

           SOLICITATION OF PROXY, REVOCABILITY AND VOTING

General

The enclosed Proxy is solicited on behalf of the Board of Directors
(the "Board" or "Board of Directors") of Supertex, Inc., a California
corporation (the "Company"), for use at the 2002 Annual Meeting of
Shareholders to be held on August 16, 2002 at 10:00 a.m., local time (the
Annual Meeting), 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 21, 2002
(the "Record Date") are entitled to notice of and to vote at the meeting.  At
the Record Date 12,593,276 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.

The Company is mailing this proxy statement and an accompanying proxy
card on or about July 15, 2002 to all shareholders entitled to vote at the
Annual 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 at the Company's principal executive offices, 1235 Bordeaux
Drive, Sunnyvale, California 94089 a written notice of revocation or a duly
executed proxy bearing a later date or (ii) by attending the meeting and
voting in person.  Attendance at the meeting will not, by itself, revoke a
proxy.

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.  The
director candidates who receive the most votes will be elected to fill the
seats on the Board.  Approval of all of the proposals requires the favorable
vote of a majority of the votes "represented and voting" at the Annual Meeting
(the "Votes Cast").  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, in the absented contrary controlling authority, 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.  A broker "Non-Vote" occurs when a nominee holding shares for a
beneficial owner does not vote on a particular proposal because the nominee
does not have discretionary power with respect to that item and has received
no instruction from the beneficial owner.

Accordingly, in general abstentions and broker "non-votes" will not
affect the outcome of the voting on a proposal that requires a majority of
the Votes Cast.  However, the number of shares voting favor of any matter
must constitute at least a majority of the require quorum for the Annual
Meeting.  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 2003
must be received by the Company no later than February 21, 2003 in order to be
considered by the Company's management to be included in the proxy statement
and form of proxy relating to that meeting. The proposal must be mailed to
our principal offices, 1235 Bordeaux Drive, Sunnyvale, California 94089.
Such proposals may be in next year's proxy statement if they comply with the
certain rules and regulations promulgated by the Securities and Exchange
Commission.



                   PROPOSAL 1:  ELECTION OF DIRECTORS

Nominees

A board of six directors is to be elected at the Annual Meeting.  Unless
otherwise instructed, the proxy holders will vote the proxies received by
them for the Company's six nominees named below.  The six 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 and/or votes are cumulated, 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 or until such person's successor has
been elected and qualified.  The names of the nominees and certain information
about them are set forth below:

The space is in turn subleased to our epitaxial deposition service provider at
essentially the same cost.  Previously we leased the entire building,
consisting of approximately 20,000 sq.ft.  The total rental expenses paid to
Fortuna Realty Co. were $457,000, $408,000 and $388,000 in fiscal years 2002,

(1) Options granted under the Company's 1991 Stock Option Plan typically have
    a 7-year term, vest over a 5-year period of employment and have an
    exercise price equal to the market value of the Company's Common Stock on
    the date of grant.
(2) In fiscal year 2002, the Company granted options representing 318,590
    shares to employees.
(3) Potential realizable value is based on Black - Scholes Multiple Option
    model.  These values are calculated based on requirements promulgated by
    the Securities and Exchange Commission and do not reflect the Company's
    estimate of future stock price appreciation.
(4) Options granted to David Schie include an option to purchase 12,000 that
    will expire on September 1, 2003.

In March 1998, Franklin Gonzalez, the Company's Vice President, Process
Technology, and William Ingram, the Company's Vice President, Wafer Fab
Operation, were given the opportunity to exchange their older higher priced
incentive stock options for new incentive stock options at the then current
market price of $10.625 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 believed that it was in the best interest of
the Company and the shareholders of the Company to highly motivate the two
officers at the time and to make a special exchange offer that was not
available to the rest of the officers of the Company.

The following table provides the specified information concerning repricing of
options to purchase the Company's Common stock held by any executive officer
of the Company in the last 10 years.

                Report of the Executive Compensation Committee
                         of the Board of Directors

Notwithstanding anything to the contrary set forth in any of the Company's
previous filings under the Securities Act of 1933 as amended, or the
Securities Exchange Act of 1934, as amended that might incorporate future
filings, including this Proxy Statement, in whole of report, the following
report shall not be deemed to be incorporated by reference in to any such
filings.

The Executive Compensation Committee of the Board of Directors is generally
responsible for reviewing compensation and benefits, including stock options,
of executive officers of the Company.  All the members of the Board of
Directors review the stock compensation of outside directors.

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 the committee 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 vital to the
        success of the Company.  As such, the Executive 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 Executive 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 and all other officers were
        compensated within the low-to-middle salary range levels during fiscal
        2002.  The chief executive and all other executive officers of the
        Company largely met their individual goals and the Company's overall
        performance set for them in fiscal year 2002.

        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 21, 2002, the
        Company has made twenty-six 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 2002 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 Executive
                       Compensation Committee

                        Report of the Audit Committee
                         of the Board of Directors


Notwithstanding anything to the contrary set forth in any of the Company's
previous filings under the Securities Act of 1933, as amended, or the
Securities Exchange Act of 1934, as amended, that might incorporate future
filings, including this Proxy Statement, in whole or in part, the following
Audit Committee Report shall not be incorporated by reference into any such
filings, nor shall it be deemed to be soliciting material or deemed filed
with the Securities and Exchange Commission under the Securities Act of 1933,
as amended, or under the Securities Exchange Act of 1934, as amended.

In accordance with its written charter adopted by the Board of Directors of
the Company  (the "Board"), the Audit Committee of the Board (the "Committee")
assists the Board in fulfilling its responsibility for oversight of the
quality and integrity of the accounting, auditing and financial reporting
practices of the Company.  During the fiscal year ended March 31, 2002, the
Committee met five times, and discussed the interim financial information
contained in each quarterly earnings announcement with the chief financial
officer, controller and PricewaterhouseCoopers LLP, our independent auditors,
prior to public release.

In discharging its oversight responsibility as to the audit process, the
Committee obtained from PricewaterhouseCoopers LLP a formal written statement
relating to relationships between PricewaterhouseCoopers LLP and the Company
that might bear on the auditors' independence, consistent with the
Independence Standards Board Standard No. 1, "Independence Discussions with
Audit Committees," discussed with the PricewaterhouseCoopers LLP any
relationships that may impact their independence and satisfied itself as to
the auditors' independence.  The Committee also discussed with management,
and PricewaterhouseCoopers LLP the quality and adequacy of the Company's
internal controls.  The Committee reviewed with PricewaterhouseCoopers LLP
their audit plans, audit scope and identification of audit risks.

The Committee discussed with PricewaterhouseCoopers LLP all matters required
to be discussed as described in Statement on Auditing Standards No. 61, as
amended, "Communication with Audit Committees" and, with and without
management present, discussed and reviewed the results of the independent
auditors' examination of the financial statements.

The Committee reviewed the audited financial statements of the Company as of
and for the fiscal year ended March 31, 2002, with management and
PricewaterhouseCoopers LLP.  Management has the responsibility for the
preparation of the Company's financial statements and PricewaterhouseCoopers
LLP have the responsibility for the examination of those statements.

Based on the above-mentioned review and discussions with management and
PricewaterhouseCoopers LLP, the Committee recommended to the Board that the
Company's audited financial statements be included in its Annual Report on
Form 10-K for the fiscal year ended March 31, 2002, for filing with the
Securities and Exchange Commission.

Each of the members of the Audit Committee is independent as defined in
Rule 4200(a)(14) of the National Association of Securities Dealers'
Marketplace Rules.


- - Respectfully submitted by the members of the Audit Committee
                                                             W. Mark Loveless

                                                             Milton Feng


      PROPOSAL 2: RATIFICATION OF APPOINTMENT OF INDEPENDENT ACCOUNTANTS

On recommendation of the Audit Committee, the Board of Directors has selected
PricewaterhouseCoopers LLP, as independent public accountants to audit the
financial statements of the Company for the fiscal year ending March 29, 2003.
PricewaterhouseCoopers LLP, was the Company's independent public accountants
for the fiscal year ending March 31, 2002.  Representatives of
PricewaterhouseCoopers LLP are expected to be present at the Annual Meeting
to make a statement if they desire to do so and are expected to be available
to respond to appropriate questions.

Accountants Fees.  The following table sets forth the aggregate fees billed
or to be billed by PricewaterhouseCoopers LLP for the following services
during fiscal 2002:

         Description of Services                                Fees
         -------------------------------------------------------------
         Audit fees (1)                                     $  169,700
         Financial system design and implementation fees            --
         All other fees (2)                                    129,400
                                                            ----------

The Audit Committee did consider whether the provision of financial
information systems design and  implementation services and all other
non-audit services is compatible with the accountants' independence and
concluded that provision of financial information systems design and
implementation services and other non-audit services are compatible with
maintaining the independence of the Company's external auditors.
