150 V

DESCRIPTION

V_R

The 249NQ150R high current Schottky rectifier module 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,

freewheeling diodes, and reverse battery protection.
