  Units subject to the Award will vest on each of the first three anniversary
  dates of Award Date(1)Award Date:  
 (1) All share and
unit numbers are subject to adjustment under the terms of the Plan.  The Stock Units are subject to acceleration
and termination prior to vesting as provided herein.  THIS AGREEMENT is among INTERNATIONAL RECTIFIER CORPORATION, a Delaware corporation
(the Corporation), and the employee named above (the Participant), an
employee of the Corporation or one of its subsidiaries, and is delivered under
the International Rectifier Corporation 2000 Incentive Plan (Amended and
Restated as of November 22, 2004) (the Plan).  W I T N E S S E T H  WHEREAS, the Compensation and
Stock Option Committee of the Board of Directors has approved, and the
Corporation has granted, effective as of the Award Date, to the Participant
with reference to services rendered to the Company, a restricted stock unit
award under the Plan (the Stock Unit Award or Award), upon the terms and
conditions set forth herein and in the Plan.  NOW THEREFORE, in consideration
of services rendered by the Participant and the mutual promises made herein and
the mutual benefits to be derived therefrom, the parties agree as follows:  1.Defined Terms.  Capitalized terms used herein and not
otherwise defined herein shall have the meaning assigned to such terms in the
Plan.  For purposes of this Agreement, a Stock
Unit means a non-voting unit of measurement which is deemed for bookkeeping
purposes to be equivalent to one outstanding share of Common Stock of the
Corporation.  2.Grant.  Subject to the terms of this Agreement and
the Plan, the Corporation grants to the Participant a Stock Unit Award with
respect to an aggregate number of Stock Units set forth above.  The Corporation acknowledges that the
consideration for the shares payable with respect to the Stock Units on the
terms set forth in this Agreement shall be the services rendered to the Company
by the Participant prior to the applicable vesting date, the fair value of which
is not less than the par value per share of the Corporations Common Stock.  3.Vesting.  The Stock Units subject to the Award shall
vest in installments as set forth in the Vesting Schedule set forth above,
subject to earlier termination or acceleration and subject to adjustment as
provided herein.  1


4.Continuance
of Employment Required.  Except
as otherwise provided herein, the vesting schedule applicable to the Stock
Units requires continued service through each applicable vesting date as a
condition to the vesting of the applicable installment of the award and the
rights and benefits under this Agreement. 
Service for only a portion of the vesting period, even if a substantial
portion, will not entitle the Participant to any proportionate vesting or avoid
or mitigate a termination of rights and benefits upon or following a
termination of employment or service.  5.Dividend and Voting
Rights.  (a)Limitations on
Rights Associated with Units. 
The Participant shall have no rights as a stockholder of the
Corporation, no dividend rights (except as expressly provided in Section 5(b) hereof
with respect to Dividend Equivalents) and no voting rights with respect to the
Stock Units or any shares of Common Stock issuable in respect of such Stock
Units, until shares of Common Stock are actually issued to and held of record
by the Participant.  No adjustments will
be made for dividends or other rights of a holder for which the record date is
prior to the date of issuance of the stock certificate evidencing the shares.  (b)Dividend Equivalent
Distributions.  No later than
sixty (60) days following each date that the Corporation pays an ordinary cash
dividend on its outstanding Common Stock (if any ordinary cash dividends are
paid), for which the related record date occurs after the Award Date and prior
to the third anniversary of the Award Date, the Corporation shall make a cash
payment to the Participant equal to, subject to the tax withholding provisions
of Section 11 hereof and Section 5.5 of the Plan, the amount of the
ordinary cash dividend paid by the Corporation on a single share of Common
Stock multiplied by the number of Stock Units subject to this Agreement
outstanding and unpaid as of such record date (Dividend Equivalents).  6.Restrictions on
Transfer.Prior to the time the
Stock Units are vested and paid, neither the Stock Units comprising the Award
nor any other rights of the Participant under this Agreement or the Plan may be
transferred, except as expressly provided in Section 1.9 of the Plan.  No specific exception to the general transfer
prohibitions set forth in Section 1.9 of the Plan has been authorized by
the Committee.  7.Timing
and Manner of Payment with Respect to Stock Units. Stock Units subject
to this Agreement will be paid in an equivalent number of shares of Common
Stock within 60 days after the vesting of such Stock Units in accordance with
the terms hereof, subject to adjustment as contemplated by Section 9 and
subject to earlier payment pursuant to Section 10.  The Participant or other person entitled
under the Plan to receive the shares shall deliver to the Corporation any
representations or other documents or assurances required pursuant to Section 5.4
of the Plan.  8.Effect
of Termination of Employment or Change in Control.  (a)Forfeiture
after Certain Events.  The
Participants Stock Units shall be extinguished to the extent such Stock Units
have not become vested upon the date the Participant is no longer employed by
the Corporation or one of its Subsidiaries, regardless of the reason for such
termination of employment, whether with or without cause, voluntarily or
involuntarily; provided, however, that if the Participant incurs a permanent
and total disability or dies while employed by the Corporation or a Subsidiary,
or retires with the consent of the Corporation or a Subsidiary from employment
by the Corporation or a Subsidiary, then if the Stock Units subject to the
Award are not then otherwise fully vested the next scheduled vesting
installment of such Stock Units shall become vested upon such termination of
employment.  If the Participant is  2


employed by an entity that is a Subsidiary and such
entity ceases to be a Subsidiary, such event shall be deemed to be a
termination of employment of the Participant unless the Participant otherwise
continues following such event to be employed by the Corporation or another
Subsidiary that continues as such following the event.  Absence from work caused by military service,
authorized sick leave or other leave approved in writing by the Committee shall
not be considered a termination of employment by the Corporation or a
Subsidiary for purposes of this Section 8.  (b)Termination of Stock
Units.  If any Stock Units are
extinguished hereunder, such unvested, extinguished Stock Units, without
payment of any consideration by the Corporation or any Subsidiary, shall
automatically terminate and be cancelled without any other action by the Participant,
or the Participants beneficiary, as the case may be.  (c)Acceleration
Upon Change in Control.  Upon the
occurrence of (or, as the circumstances may require, immediately prior to) a
Change in Control (as defined below), then any portion of the Stock Units
subject to the Award that have not previously vested or terminated shall
thereupon vest, unless prior to the Change in Control the Committee determines
that benefits under this or other awards will not accelerate upon occurrence of
the Change in Control or determines that only certain or limited benefits under
some or all awards will be accelerated and the extent to which they will be
accelerated, and/or establishes a different time in respect of the Change in
Control for such acceleration.  The Committee
may accord the Participant a right to refuse any acceleration pursuant to this
Agreement, in such circumstances as the Committee may approve.  For purposes of this Agreement, Change in
Control means any of the following:  (a) approval
by the stockholders of the Corporation of the dissolution or liquidation of the
Corporation; (b) approval by the stockholders of the Corporation of an
agreement to merge or consolidate, or otherwise reorganize, with or into one or
more entities that are not majority-owned subsidiaries of the Corporation, as a
result of which 50% or less of the outstanding voting securities of the
surviving or resulting entity are, or are to be, owned by former stockholders
of the Corporation; (c) approval by the stockholders of the Corporation of
the sale or transfer of substantially all of the Corporations business and/or
assets to a person or entity that is not a Subsidiary of the Corporation; or (d) the
occurrence of any of the following: (i) any person, alone or together
with all affiliates and associates of such person, without the prior
approval of the Board, becomes the beneficial owner of more than 50% of the
outstanding voting securities of the Corporation (the terms person, affiliates,
associates and beneficial owner are used as such terms are used in the
Securities Exchange Act of 1934 and the General Rules and Regulations
thereunder); provided, however, that Change in Control shall not be deemed to
have occurred if such person is the Corporation, any Subsidiary or any
employee benefit plan or employee stock plan of the Corporation or of any
Subsidiary, or any trust or other entity organized, established or holding
shares of such voting securities by, for, or pursuant to the terms of any such
plan, or any member of or entity or group affiliated with the Lidow family; or (ii) individuals
who at the beginning of any period of two consecutive calendar years constitute
a majority of the Board cease for any reason, during such period, to constitute
at least a majority thereof, unless the election, or the nomination for
election by the Corporations stockholders, of each new Board member was
approved by a vote of at least two-thirds of the Board members then still in
office who were Board members at the beginning of such period.  9.Adjustments in
Case of Changes in Common Stock. 
The Committee may adjust the number of Stock Units subject to this
Agreement as provided under Section 5.2 of the Plan.  Upon the occurrence of an Event (as defined
below), the Committee shall make adjustments as it deems appropriate in the
number and kind of securities or other consideration that may become payable
with respect to the Award.  If any
adjustment shall be made under Section 5.2 of the Plan or an Event shall
occur and the Stock Unit Award has not been fully  3


vested and paid upon such Event or prior thereto, the
Stock Unit Award may become payable in securities or other consideration (the Restricted
Property) rather than in the Common Stock otherwise payable in respect of the
Stock Unit Award.  Such Restricted
Property shall become payable at the times and in such proportions set forth in
Section 7 above or such earlier time as the Committee may authorize
pursuant to Section 10 below. 
Notwithstanding the foregoing, to the extent that the Restricted
Property includes any cash, the commitment hereunder shall become an unsecured
promise to pay an amount equal to such cash (with earnings attributable thereto
as if such amount had been invested, pursuant to policies established by the
Committee, in interest bearing, FDIC insured (subject to applicable insurance
limits) deposits of a depository institution selected by the Committee) at such
times and in such proportions as the Stock Unit Award becomes payable in
accordance with Section 7 above. 
Notwithstanding the foregoing, the Stock Unit Award and any Common Stock
or other securities or property payable in respect of the Stock Unit Award
shall continue to be subject to proportionate and equitable adjustments (if
any) under Section 5.2 of the Plan consistent with the effect of such
events on stockholders generally, as the Committee determines to be necessary
or appropriate, and in the number, kind and/or character of shares of Common
Stock or other securities, property and/or rights payable in respect of Stock
Units granted under the Plan.  All rights
of the Participant hereunder are subject to those adjustments.  For purposes of this Agreement, Event means
a liquidation, dissolution, Change in Control, merger, consolidation, or other
combination or reorganization, or a recapitalization, reclassification,
extraordinary dividend or other distribution (including a split up or a spin
off of the Corporation or any significant Subsidiary), or a sale or other
distribution of substantially all the assets of the Corporation as an entirety.  10.Possible
Early Settlement of Award.  The
Committee retains the right to accelerate the vesting and payment date of the
outstanding and previously unvested Stock Units subject to the Award in
connection with an Event, a Change in Control, or the termination of the
Participants employment with the Corporation or one of its Subsidiaries.  This Section 10 is not intended to
prevent vesting of the Award pursuant to Section 8(c) above or an
adjustment to the Award as provided in the Plan or Section 9 above.  11.Tax Withholding.  Upon payment of Dividend Equivalents and/or
the distribution of shares of Common Stock in respect of the Stock Units, the
entity within the Company last employing the Participant shall have the right
at its option to (a) require the Participant (or the Participants
beneficiary, as the case may be) to pay or provide for payment in cash of the
amount of any taxes which the Company may be required to withhold with respect
to such payment or distribution or (b) deduct from any amount payable to
the Participant the amount of any taxes which the Company may be required to
withhold with respect to such payment or distribution.  In any case where a tax is required to be
withheld in connection with the delivery of shares of Common Stock under this
Agreement, the Committee may, but is not required to, reduce the number of
shares to be delivered by (or otherwise reacquire) the appropriate number of
shares valued at their then Fair Market Value, to satisfy such withholding
obligation.  12.Notices.  Any notice to be given under the terms of
this Agreement shall be in writing and addressed to the Corporation at its
principal office located at 233 Kansas Street, El Segundo, California 90245, to
the attention of the Assistant Secretary and to the Participant at the address
given beneath the Participants signature hereto, or at such other address as
either party may hereafter designate in writing to the other.  4


13.Plan and Program.  The Award and all rights of the Participant
with respect thereto are subject to, and the Participant agrees to be bound by,
all of the terms and conditions of the provisions of the Plan, incorporated
herein by reference, to the extent such provisions are applicable to Awards
granted to employees.  The Participant
acknowledges receipt of a copy of the Plan, which is made a part hereof by this
reference, and agrees to be bound by the terms thereof.  Unless otherwise expressly provided in other
Sections of this Agreement, provisions of the Plan that confer discretionary
authority on the Committee do not (and shall not be deemed to) create any
rights in the Participant unless such rights are expressly set forth herein or
are otherwise in the sole discretion of the Committee so conferred by
appropriate action of the Committee under the Plan after the date hereof.  If there is any conflict or inconsistency
between the terms and conditions of this Agreement and of the Plan, the terms
and conditions of the Plan shall govern.  14.No
Service Commitment by Company. 
Nothing contained in this Agreement or the Plan constitutes an
employment commitment by the Corporation or any of its Subsidiaries, affects
the Participants status as an employee at-will who is subject to termination
without cause, confers upon the Participant any right to remain employed by the
Corporation or any Subsidiary, interferes in any way with the right of the Corporation
or any Subsidiary at any time to terminate such employment, or affects the
right of the Corporation or any Subsidiary to increase or decrease the
Participants other compensation.  15.Limitation on
Participants Rights.Participation
in the Plan confers norights or
interests other than as herein provided. 
This Agreement creates only a contractual obligation on the part of the
Corporation as to amounts payable and shall not be construed as creating a
trust.  The Plan, in and of itself, has
no assets.  The Participant shall have
only the rights of a general unsecured creditor of the Corporation (or
applicable Subsidiary) with respect to amounts credited and benefits payable,
if any, with respect to the Stock Units, and rights no greater than the right
to receive the Common Stock (subject to adjustments) as a general unsecured
creditor with respect to Stock Units, as and when payable hereunder.  IN
WITNESS WHEREOF, the parties have executed this Agreement as
of the date first above written.  By the
Participants execution of this Agreement, the Participant agrees to the terms
and conditions hereof and of the Plan.  INTERNATIONAL RECTIFIER
