IXYS Adds 800V Versions of Its PolarHV(TM) Power MOSFETs

IXYS Corporation (NASDAQ:SYXI) announced today the
release of new 800V PolarHV Power MOSFETs that bring additional design
flexibility to a broad range of higher power conversion applications.
The PolarHV platform incorporates IXYS' proprietary technology that
reduces on-resistance by 30%, enabling improved efficiency. These new
Power MOSFETs extend the PolarHV portfolio into the high voltage power
conversion market.
   IXYS' new 800V PolarHV Power MOSFETs cover a broad range of power,
with over 50 parts to choose from in both Standard and HiPerFET
versions. HiPerFET models feature a fast intrinsic body diode for low
Qrr and improved hard-switching efficiency. All of these Power MOSFETs
are offered in standard packages and a variety of IXYS ISOPLUS
packages with integral backside case isolation. The IXFC16N80P (800V,
9A, Rdson = 0.65 ohm with isolated Rth,jc = 0.9K/W) and IXFR44N80P
(800V, 25A, Rdson = 0.2 ohm with isolated Rth,jc = 0.42K/W) are just
some examples of ISOPLUS PolarHV HiPerFET Power MOSFETs with superior
electrical and thermal performance.
   "We extended our capability to use a standard CMOS memory wafer
fab to design and produce these advanced power MOSFETs. IXYS pioneered
the fabless model for a power semiconductor company as a business
model, and have been using CMOS IC fabs since 1984. The fact that our
scientists are able to produce state of the art power MOSFETs in these
fabs, offers our customers excellent performance/price ratio
advantages which result in better energy efficiency in power systems,"
commented Dr. Nathan Zommer IXYS CEO.
   IXYS' 800V PolarHV Power MOSFETs will be valuable in a variety of
applications, with best-in-class performance and competitive pricing.
Common 800V applications include DC-DC converters, high voltage
lighting, industrial machinery and medical equipment. The superior
ruggedness and safe operating area of the PolarHV Power MOSFETs will
be of additional benefit in applications with challenging operating
conditions. The value of the larger, high-current MOSFET is enhanced
by the fact that they are competitively priced, without the cost
premium traditionally associated with high voltage MOSFETs. IXYS will
continue to grow the high voltage product line, with an ongoing plan
to increases the value offered in the PolarHV market.
