Description/ Features

This center tap Schottky rectifier has been optimized for low

reverse leakage at high temperature. 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.
