		               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 2003 Annual Meeting of
Shareholders to be held on August 15, 2003 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.

	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) 222-8888.

	The Company is mailing this proxy statement and an accompanying proxy
card on or about July 14, 2003 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.

Solicitation

	The Company will bear the entire cost of preparing, assembling,
printing and mailing this Proxy Statement, the accompanying proxy and any
additional material that may be furnished to shareholders.  Copies of
solicitation material will be furnished to brokerage houses, fiduciaries and
custodians to forward to beneficial owners of stock held in the names of such
nominees.  The Company may retain the services of an outside proxy
solicitation firm at an estimated cost of approximately $10,000 to $15,000.
The solicitation of proxies may also be made by the use of the mails and
through direct communication with certain shareholders or their
representatives by officers, directors and employees of the Company, who will
receive no additional compensation for such solicitation.  This proxy and the
accompanying form of proxy are being mailed to shareholders on or about
July 14, 2003.

Voting

	Only shareholders of record at the close of business on June 20, 2003
(the "Record Date") are entitled to notice of and to vote at the meeting.  On
the Record Date, 12,705,704 shares of the Company's Common Stock, no par
value, were issued and outstanding.  Therefore, the presence at the Annual
Meeting, either in person or by proxy, of a majority or 6,352,853 shares of
Common Stock will constitute a quorum for the transaction of business at the
Annual Meeting.  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 absence of 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.

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 2004
must be received by the Company no later than March 9, 2004 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 as follows:

passed by unanimous written consent.  All directors attended each meeting

Purchase Plan (the "ESPP") Committee, and a Deferred Compensation Plan

Audit Committee

	The Audit Committee consists of three non-employee directors, W. Mark

reviews the arrangements for and scope of the audit by the Company's
independent accountants and reviews their independence, and generally oversees
the integrity and quality of the Company's financial accounting and reporting
practices and its system of internal accounting controls.  It is not the duty
of the Audit Committee to plan or conduct audits or to determine that the
Company's financial statements are complete and accurate and are in accordance
with generally accepted accounting principles.  Management is responsible for
the Company's financial statements and the reporting process, including the
system of internal controls.  The independent auditors are responsible in
their report for expressing an opinion on the conformity of those financial
statements with generally accepted accounting principles.  The
responsibilities of the Audit Committee are more fully described in the Audit
Committee's written charter, which was approved by the Board of Directors in
fiscal year 2001 and included as Appendix A to the Proxy Statement for the
Company's 2001 annual meeting of shareholders.

the listing standards of the National Association of Securities Dealers, Inc.

Company's directors, is the President of Elliott Schlam Associates.  There is
no long-term consulting contract between Mr. Schlam and the Company.   Payment
made to Mr. Schlam during the fiscal year 2003 represents consulting services
rendered during the fiscal year.

	Stock Option Grant.  The Company did not grant stock options to any
director during fiscal year 2003.

Certain Relationship and Related Transactions

	The Company leased a portion of a building, consisting of approximately
5,600 sq. ft at 1225 Bordeaux Drive, Sunnyvale, California under an operating
lease from Fortuna Realty Co, a corporation owned by a former Supertex
Director, Yunni Pao, who beneficially owns more than 5% of the Company's Common
Stock, as more fully set forth in the following page under "Securities
Ownership of Certain Beneficial Owners and Management."  The lease will expire
on April 1, 2007, which coincides with our Sublease Agreement with Reaction
Technology, 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
$135,000, $457,000, and $408,000 in fiscal years 2003, 2002 and 2001,

start date of the option to one year after the original vesting date for the

officers at the time and to make a special exchange offer that was not
available to the rest of the officers of the Company.

		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 into 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.  Executives 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 executive 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 executive officers by reviewing the
	compensation levels for competitive positions in the market.  Based on
	comparative data, the chief executive and other executive officers were
	compensated within the low-to-middle salary range levels during fiscal
	2003.  The chief executive and executive officers of the Company
	largely met their individual goals and the Company's overall
	performance set for them in fiscal year 2003 although none were granted
	any salary increase.

		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 24, 2003, 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 existing employees for performance and
	promotions, and as a part of the employment compensation package for
	new employees.  The Committee chose not to grant stock options to any
	officer during fiscal 2003 due to the Company's performance which was
	in large part impacted by the weak economic conditions, in particular,
	in the semiconductor industry.


Chief Executive Officer Compensation

	In accordance with the compensation philosophy stated above and the
Company's results, Mr. Henry Pao's base salary during fiscal year 2003 was
$245,855, which was the same salary he earned during fiscal year 2002. His base
salary is designed to be competitive with base salaries paid to other chief
executive officers of corporations with similar size and sales volume within
the semiconductor industry, most of which are included in the Nasdaq Electronic
Component Index, although Mr. Pao has the added responsibility of the
Company's Chief Financial Officer without extra compensation.

	The Executive Compensation Committee establishes performance goals and
objectives for the CEO each year and assesses his accomplishments of previously
established objectives on a yearly basis.  Company performance is a significant
portion of each year's objectives, with the remaining elements reflecting
matters most important to the Company.  This process is the basis for
determining the amount of any bonus awarded to the CEO.  Mr. Pao did
not received a bonus in fiscal year 2003

	As to the equity component of his compensation, the Executive
Compensation Committee did not grant Mr. Pao options during fiscal
2003.

			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.

	The Audit Committee is comprised entirely of outside, independent
directors.  On behalf of the Board of Directors, the Audit Committee retains
the Company's independent accountants, reviews the arrangements for and scope
of the audit by the Company's independent accountants and reviews their
independence, and generally oversees the integrity and quality of the
Company's financial accounting and reporting practices and its system of
internal accounting controls.  It is not the duty of the Audit Committee
to plan or conduct audits or to determine that the Company's financial
statements are complete and accurate and are in accordance with generally
accepted accounting principles.  Management is responsible for the Company's
financial statements and the reporting process, including the system of
internal controls.  The independent auditors are responsible in their report
for expressing an opinion on the conformity of those financial statements with
generally accepted accounting principles.

	During the fiscal year ended March 31, 2003, the Committee met six
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 the written disclosures
and the letter from the independent accountants required by the Independence
Standards Board Standard No. 1, "Independence Discussions with Audit
Committees," has discussed with the PricewaterhouseCoopers LLP their
independence and has 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, 2003, with management and
PricewaterhouseCoopers LLP.   Based on this review and the above-mentioned
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,
2003, 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.

 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 27, 2004.  PricewaterhouseCoopers LLP, was the Company's independent
public accountants for the fiscal year ending March 31, 2003.  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 2003:

             Description of Services		  		  Fees


	Audit fees (1)						$  222,419
	Financial system design and implementation fees                 --
	All other fees (2)					   145,528
								  --------
	Total							$  367,947
								  --------

	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.


(1) Audit Fees represents the aggregate fees billed or to be billed for
    professional services rendered for the audit of our fiscal 2003 annual
    financial statements and for the review of the financial statements
    included in our quarterly reports during such period.

(2) All Other Fees represents the aggregate fees billed in fiscal 2003 for
    services other than audit and other than financial information system
    design and implementation including, for example, fees for tax compliance
    of $45,425 and tax consulting of $100,103.


Board Recommendation on Proposal 2: Vote Required

	The ratification of the appointment of PricewaterhouseCoopers LLP as
the Company's independent auditors for the fiscal year ending March 27, 2004,
