Product of the month: IXYS Adds 800V Versions of its PolarHVTM Power MOSFETs

BetaTHERM Sensors – L Series Lead-Frame ThermistorIXYS Corporation (NASDAQ: SYXI) have just announced 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 ISOPLUSTM packages with integral backside case isolation. The IXFC16N80P (800V, 9A, Rdson = 0.65Ω with isolated Rth,jc = 0.9K/W) and IXFR44N80P (800V, 25A, Rdson = 0.2Ω with isolated Rth,jc = 0.42K/W) are just some examples of ISOPLUS PolarHV HiPerFET Power MOSFETs with superior electrical and thermal performance.

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 areas of the PolarHV Power MOSFETs will be of additional benefit in applications with challenging operating conditions. The value of the 800V MOSFET is further 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 increase the value offered in the PolarHV family.

"We extended our capability to use a standard CMOS memory wafer fab in designing and producing these advanced power MOSFETs. IXYS pioneered the "fabless" business model for power semiconductor companies, and have been using CMOS IC fabs since 1984. Our scientists and engineers are able to produce state-of-the-art power MOSFETs in these fabs that offer our customers excellent performance/price ratio advantages, which result in better energy efficiency in power systems," commented Dr. Nathan Zommer - IXYS CEO.
