SCHOTTKY RECTIFIER 40 Amp
Major Ratings and Characteristics Characteristics
IF(AV) Rectangular waveform VR R M IFSM @ tp = 5 µs sine VF TJ @ 20 Apk, TJ = 125 °C
Description/Features Units
A V A V °C This center tap Schottky rectifier has been optimized for ultra low forward voltage drop specifically for 3.3V output power supplies. The proprietary barrier technology allows for reliable operation up to 150 °C junction temperature. Typical applications are in parallel switching power supplies, converters, reverse battery protection, and redundant power subsystems. Center tap configuration Optimized for 3.3V application Ultra low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance 150 °C TJ operation
