person.  However, to ensure your representation at the meeting,

card as promptly as possible in the enclosed postage-prepaid

				 BY ORDER OF THE BOARD OF DIRECTORS

				    /s/ Benedict C. K. Choy
					Secretary


Sunnyvale, California
July 1, 1998



			    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 1998 Annual Meeting of Shareholders
to be held on August 7, 1998 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 8,
1998 (the "Record Date") are entitled to notice of and to vote
at the meeting.  At the Record Date, 12,102,014 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
1, 1998 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.



 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 1999 must be received by the Company no later
than March 3, 1999 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 and until such person's successor has been elected
and qualified.  The names of the nominees and certain
information about them are set forth below.

Board Meetings and Committees

 The Board of Directors of the Company held a total

can make nominations.

Audit Committee

 The Audit Committee consists of two outside directors, Yunni
Pao and Frank Pao, and Benedict Choy, an inside director who has
no influence on and is not involved in the Company's financial
matters.  The principal functions of the Audit Committee are (1)
to monitor corporate financial reporting and the internal and
external audits of the Corporation (2) to review and evaluate
the Company's internal control structure, and (3) to nominate

performed by such auditors.  The Audit Committee held one

Pao, and Benedict Choy.  The Compensation Committee is

with respect to all cash-based compensation of the executive
officers of the Company and all stock compensation of employees
other 



than the executive officers.  It also serves as an administrator 
of the Company's employee stock option plans.  The Compensation 
Committee held one meeting in fiscal year 1998, and such meeting 
was  attended by all Compensation Committee members.

Compensation Committee Interlocks and Insider Participation

 Benedict Choy and Henry C. Pao serve on the Compensation
Committee and are also officers of the Company.  Yunni Pao, the
father of Henry Pao and Frank Pao, is a member of the Company's

and Frank Pao, serves as an administrative arm of the Board of
Directors to authorize the grant of stock options under the
Company's 1991 Stock Option Plan to officers and directors of
the Company eligible to receive options under such Plan.

       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
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 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
officers by reviewing the compensation levels for competitive
positions in the market.  Based on comparative data, officers
were compensated within the low-to-middle salary range levels
during fiscal 1998.  Executive officers of the Company largely
met their individual goals and the Company's overall performance
set for them in fiscal 1998.

Profit-Sharing Bonus.  The Company has a semiannual
profit-sharing plan under which it distributes to all employees,
including executive 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 July 1, 1998, the Company has made
twenty one consecutive semiannual profit-sharing distributions.

Equity-Based Compensation:

Stock Option Grants.  Stock options provide additional
incentives to 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 1998 for
performance and promotions of existing employees, and as a part
of the employment compensation package for new employees.

			   - The Compensation Committee

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

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.  Rental expense was
approximately $315,000, $321,000, and $473,000, (net of sublease
income of $49,000, 



$105,000, and $86,000, respectively) in fiscal 1998, 1997, and 
1996, respectively.  Future estimated rental payments before 
sublease income are $374,000  for fiscal 1999.

Compliance with Section 16(a) of the Exchange Act

 Section 16(a) of the Securities Exchange Act of 1934 (the
"Exchange Act") requires the Company's officers and directors,
and persons who own more than 10% of the Company's Common Stock
to file with the Securities and Exchange Commission ("SEC") and
the National Association of Securities Dealers ("NASD") initial
reports of ownership on Form 3 and changes in ownership on Form
4 or 5.   Such officers, directors and 10% stockholders are also
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 28, 1998, all
Section 16(a) filing requirements applicable to its officers,
directors, and 10% shareholders were satisfied.

Compensation of Executive Officers

 The following table shows compensation paid to  the Company's
