                          September Quarter

    Seventh Consecutive Quarter of Revenue Growth

    SANTA CLARA, Calif.--(BUSINESS WIRE)--Nov. 6, 2007--IXYS
Corporation (NASDAQ:IXYS) today reported record net revenues of $76.2
million for the second fiscal quarter ended September 30, 2007, an
increase of 6.0% as compared with net revenues of $71.9 million for
the same period in the prior fiscal year. This is the seventh quarter
of consecutive revenue growth for the company.

    For the six months ended September 30, 2007, IXYS reported net
revenues of $152.1 million, an increase of 8.9% as compared with net
revenues of $139.6 million for the same period in the prior fiscal
year.

    "Our consistent revenue growth is attributable to our broad
spectrum of power products, which have gained widespread adoption by
our long-standing customers. Simultaneously, we have worked to build
new customer and distributor relationships," stated Dr. Nathan Zommer,
President and CEO of IXYS. "As we make greater efforts to cross-sell
our divisional products and introduce new technologies, we are
experiencing increased product demand, which resulted in record
backlog."

    Highlights for the quarter ended September 30, 2007:

    --  Record revenues of $76.2 million, marking the seventh
        consecutive quarter of revenue growth

    --  Record backlog of $109.9 million

    --  IXYS repurchased 277,000 shares for $2.7 million

    Gross profit was $20.0 million, or 26.3% of net revenues, for the
quarter ended September 30, 2007, as compared to gross profit of $22.1
million, or 30.8% of net revenues, for the same quarter in the prior
fiscal year. Gross profit for the six months ended September 30, 2007
was $42.4 million, or 27.9% of net revenues, as compared to a gross
profit of $44.0 million, or 31.5% of net revenues, for the same period
in the prior fiscal year.

    "While IXYS' main business lines proved resilient against a
volatile market, our IC business underperformed in the September 2007
quarter, particularly our ASIC products and telecom ICs," commented
Dr. Nathan Zommer.

    Net income for the quarter ended September 30, 2007, was $3.9
million, or $0.12 per diluted share, as compared to $3.8 million, or
$0.11 per diluted share, for the same quarter in the prior fiscal
year. Net income for the six months ended September 30, 2007 was $11.0
million, or $0.33 per diluted share, as compared to net income of
$28.1 million, or $0.79 per diluted share, for the same period in the
prior fiscal year.

    The results for the six months ended September 30, 2007 included
net credit adjustments to litigation provision of $6.0 million.
Results for the same period in the prior fiscal year included net
credit adjustments to litigation provision of $36.6 million.

    The company repurchased approximately 277,000 IXYS shares for $2.7
million during the September 2007 quarter, and approximately 517,000
IXYS shares for $5.0 million in the six months ended September 2007.
"As of September 30, 2007, 1.4 million shares remained available for
repurchase under the existing repurchase authorization. We plan to
continue buying back shares under our authorized stock repurchase
program," commented Uzi Sasson, COO and CFO.

    "Our goals remain constant: gain market share by cross selling our
power products, seek out higher margin business, reduce operating
costs and continue overall company growth," stated Mr. Sasson. "We are
aware of the current market volatility and macroeconomic trends
affecting the semiconductor industry generally. In that vein, we
project revenues for the December 2007 quarter to be relatively flat
as compared to the September 2007 quarter."
