Description/ Features
This 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 configuration
Very low forward voltage drop
High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
High frequency operation
Guard ring for enhanced ruggedness and long term
reliability
