EL SEGUNDO, Calif. -- December 10, 2012

International Rectifier Corporation (“IR”) (NYSE:IRF) today announced the
appointment of Gary Tanner as Executive Vice President and Chief Operations
Officer, effective January 2, 2013. Mr. Tanner, 60, will report directly to
Oleg Khaykin, President and Chief Executive Officer, and will be responsible
for the continued implementation of the Company’s operational transformation
strategy. Mr. Tanner will succeed Mike Barrow, 58, who will now lead the
Company’s efforts to commercialize its gallium nitride on silicon (GaN)
technology.

“As we position IR for the next phase of growth, the execution of our
operational transformation strategy and the successful launch of our GaN
technology platform will be two of our major focus areas,” said Oleg Khaykin,
International Rectifier’s President and Chief Executive Officer. “Both Gary
and Mike have outstanding track records in the semiconductor industry and I am
confident in their leadership and management capabilities to drive two of our
most critical initiatives.”

“I am excited about the opportunity to join International Rectifier and help
build upon the strong foundation that is already in place,” said Gary Tanner.
“I look forward to working with IR’s talented operations team to continue
implementing our operational transformation strategy. We believe that doing so
will allow us to re-size our operations, reduce costs, effectively scale the
business during an up-cycle and significantly reduce the downward margin
pressure during a down cycle.”

Mr. Tanner brings over 35 years of semiconductor industry experience to IR and
most recently served as Chief Executive Officer at Zarlink Semiconductor Inc.,
which was acquired by Microsemi Corporation in October, 2011. Prior to his
role as Chief Executive Officer, Mr. Tanner served as Chief Operating Officer
where he was responsible for increasing Zarlink’s operational efficiency and
streamlining operations. Mr. Tanner joined Zarlink in 2007 as Senior Vice
President of Worldwide Operations via the acquisition of Legerity where he
served as the Head of Operations. Before Zarlink, Mr. Tanner worked for nine
years at Intel Corporation, where he held various positions managing domestic
and international manufacturing operations. Prior to Intel, Mr. Tanner held
various management positions in fab operations at National Semiconductor,
Texas Instruments and NCR. Mr. Tanner holds a Bachelor of Science degree in
Technical Management from Regis College.

GaN Commercialization

“The Company has made a significant investment in developing GaN technology
over the past nine years. As we move from the research and development phase
to production, we are putting one of our most senior and talented executives
in charge of this strategic initiative to ensure the successful
commercialization of this revolutionary new technology,” stated Mr. Khaykin.
“Mike joined IR in 2008 as Executive Vice President and Chief Operations
Officer and was the principal architect of IR’s operational transformation
strategy. I thank Mike for his leadership and contribution to IR’s growth over
the past four years and look forward to his continued leadership as the
Executive Vice President of GaN Technologies and his success in
commercializing the technology. In his new role Mike will be responsible for
all aspects of GaN, including process and product development, product
marketing, and manufacturing.”

“I look forward to leading this critical strategic initiative for IR,” said
Mike Barrow. “We have a highly talented GaN technology team, a large library
of intellectual property, and have successfully validated our GaN technologies
with Tier 1 customers. The next step is for us to fully commercialize this
exciting new platform. IR is already a market leader in silicon power
management technologies and it is my goal to extend this lead and open up new
opportunities with our GaN technologies.”
