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 175°C
junction temperature. Typical applications are in switching
power supplies, converters, free-wheeling diodes, and reverse
battery protection.
