SCHOTTKY RECTIFIER 5 Amp
Major Ratings and Characteristics Characteristics
IF(AV) Rectangular waveform V R R M range IFSM @ tp = 5 µs sine VF TJ @ 5 Apk, TJ = 125°C range
Description/ Features Units
A V A V °C The 50SQ... axial leaded Schottky rectifier 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, free-wheeling diodes, and reverse battery protection. 175° C TJ operation High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance Low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability
