DESCRIPTION
These soft recovery, high speed rectifiers are ideally suited for high performance in
high voltage switching applications. The performance of these rectifiers minimize
losses in power conversion and motor control circuits complementing the switching
character of power MOSFETs, IGBTs, and bipolar transistors.
