DESCRIPTION

The VS-MBRB7... Schottky rectifier series 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, freewheeling

diodes, and reverse battery protection.
