www.irf.com
This center tap Schottky rectifier series has been optimized
for low reverse leakage at high temperature. The proprietary
barrier technology allows for reliable operation up to 175C
junction temperature. Typical applications are in switching
power supplies, converters, free-wheeling diodes, and re-
verse battery protection.
