Product overview

Description

These devices are N-channel Power MOSFETs developed using SuperMESH™ 5 technology. This revolutionary, avalanche-rugged, high voltage Power MOSFET technology is based on an innovative proprietary vertical structure. The result is a drastic reduction in on-resistance and ultra low gate charge for applications which require superior power density and high efficiency.

All features
TO-220 worldwide best R_DS(on)

Worldwide best FOM (figure of merit)

Ultra low gate charge

100% avalanche tested

Zener-protected
