Description/ Features
The 60CTQ150PbF center tap Schottky rectifier series has
been optimized for low reverse leakage at high temperature.
The proprietary barrier technology allows for reliable opera-
tion 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
Low forward voltage drop
High frequency operation
Guard ring for enhanced ruggedness and long term
reliability
