IXYS Adds High Power Versions of its PolarHT™ PolarHV™ Power MOSFETs

IXYS Corp. announced the release of new high-current PolarHT and PolarHV (hereafter PolarHT/HV) Power MOSFETs that bring additional design flexibility to a broad range of higher power conversion applications based on IXYS PolarHT/HV technology. The PolarHT/HV platform incorporates IXYS proprietary cell-design technology that reduces on-resistance by 30%, enabling improved efficiency.

IXYS provides a wide selection of these new high-current PolarHT/HV Power MOSFETs. Voltages range from 300V to 800V and currents reach as high as 140A. These Power MOSFETS are offered in a number of different packages, including the standard TO-264 and a variety of IXYS ISOPLUS™ packages, which provides integral backside case isolation. These new devices are all HiPerFET™ processed, yielding Power MOSFETs with a fast intrinsic body diode for low Qrr and enhanced dV/dt ruggedness.

IXYS PolarHT/HV Power MOSFETs bring many technical benefits and cost savings to a large number of applications. High-Current PolarHT MOSFETs will find use in a broad spectrum of battery driven, industrial, and automotive markets. The superior ruggedness and safe operating area of the PolarHT/HV Power MOSFETs will be of additional benefit in applications with challenging operating requirements.

High-Current PolarHV MOSFET applications include telecom power systems, SMPS, small dc motor control, PFC circuits and other general purpose high power applications. In many applications, these high-current devices will eliminate the need for multiple components, such as when paralleling lower current MOSFETs for high power applications; this reduces the quantity of switching devices, as well as the number of balancing and drive components. The value of these high-current MOSFETs is further enhanced by the fact that they are competitively priced, without the cost premium traditionally associated with large MOSFETs.
