SCHOTTKY RECTIFIER 2 x 20 Amps
Major Ratings and Characteristics Characteristics
IF(AV) Rectangular waveform VRRM IFSM @ tp = 5 µs sine VF TJ @ 20 Apk, TJ=125°C (per leg, Typical)
Description/ Features Units
A The 40L..CW center tap Schottky rectifier has been optimized for very low forward voltage drop, with moderate leakage. The proprietary barrier technology allows for reliable operation up to 150° C junction temperature. Typical applications are in switching power supplies. 150° C TJ operation Center tap TO-247 package
