IXYS Adds 800V Versions of Its PolarHV™ Power MOSFETs
IXYS Corp. 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 ISOPLUS packages with integral backside case isolation. The IXFC16N80P (800V, 9A, Rdson = 0.65 ohm with isolated Rth, jc = 0.9kW) and IXFR44N80P (800V, 25A, Rdson = 0.2 ohm with isolated Rth, jc = 0.42kW) 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.
The company claims that its 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 ruggedness and safe operating area of the PolarHV Power MOSFETs should 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 plans to continue to grow its high voltage product line, with an ongoing plan to increase the value offered in the PolarHV market.
