Characteristics 162CMQ030 Units The 162CMQ030 isolated, center tap Schottky rectifier mod-
ule 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 applications are in switching power supplies, convert-
ers, free-wheeling diodes, and reverse battery protection.
150 °C TJ operation
Isolated heatsink
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
Low profile, high current package
