IXYS Corporation announced the release of new high-current PolarHT and PolarHV Power MOSFETs that bring additional design flexibility to a broad range of higher power conversion applications based on IXYS PolarHT/HV technology. These new Power MOSFETs exemplify IXYS Corporation’s leadership position in the high current, high voltage power conversion market. 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 ISOPLUSTM 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 Corporation released new high‑current versions of its PolarHT and PolarHV Power MOSFET families. The devices support voltages from 300 V to 800 V and currents up to 140 A, offering improved efficiency through reduced on‑resistance and fast intrinsic body diodes.
The announcement highlights example parts such as the IXFR140N30P (300 V, 70 A, 0.026 Ω, Rth,jc 0.42 K/W) and IXFL100N50P (500 V, 90 A, 0.052 Ω, Rth,jc 0.20 K/W), available in standard TO‑264 and IXYS ISOPLUSTM packages. Applications include telecom power systems, SMPS, DC motor control, PFC circuits, and other high‑power uses.
