Description/Features
The 40CPQ... 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
150° C junction temperature. Typical applications are in
switching power supplies, converters, free-wheeling diodes,
and reverse battery protection.
150° C TJ operation
Center tap TO-247 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
