Features, Applications

IF(AV) Rectangular waveform VRRM IFSM 5 s sine 220Apk, TJ=125C (per leg) range

The 440CNQ030 center tap, high current, Schottky rectifier module has been optimized for very low forward voltage drop, with moderate leakage. The proprietary barrier technology allows for reliable operation 150 C junction temperature. Typical applications are in switching power supplies, converters, free-wheeling diodes, welding and reverse battery protection. C TJ operation Center tap module High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance Very low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability
