Major Ratings and Characteristics
The 440CMQ high current Schottky rectifier module series 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 applica-
tions are in switching power supplies, converters, free-wheeling
diodes, and reverse battery protection.
150 °C TJ operation
Center tap module - Isolated Base
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
