www.irf.com
This center tap Schottky rectifier has been optimized for very
low forward voltage drop, with moderate leakage. The propri-
etary 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.

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
