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 150C
junction temperature. Typical applications are in switching
power supplies, converters, free-wheeling diodes, and reverse
battery protection.
