Description/ Features

The 40CTQ... center tap Schottky rectifier has been optimized for very low forward voltage drop, with moderate leakage. 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

Center tap TO-220 package

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
