444CNQ... SERIES
SCHOTTKY RECTIFIER 440 Amp
TO-244AB
Major Ratings and Characteristics Characteristics
IF(AV) Rectangular waveform VRRM range IFSM @ tp = 5 µs sine VF TJ @ 220Apk, TJ=125°C (per leg) range
Description/Features
The 444CNQ 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 125 °C junction temperature. Typical applications are in high current switching power supplies, plating power supplies, UPS systems, converters, free-wheeling diodes, welding, and reverse battery protection. 125 °C TJ operation Center tap module 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
