SCHOTTKY RECTIFIER 150 Amp
D-60
Major Ratings and Characteristics Characteristics
IF(AV) Rectangular waveform VRRM range IFSM @ tp = 5 s sine VF TJ @ 75Apk, TJ = 125C (per leg) range
Description/ Features
The 151CMQ isolated center tap Schottky rectifier module series has been optimized for low reverse leakage at high temperature. The proprietary barrier technology allows for reliable operation up to 175 C junction temperature. Typical applications are in switching power supplies, converters, freewheeling diodes, and reverse battery protection. 175 C TJ operation Isolated heatsink Center tap module
