Description/ Features

The 249NQ...(R) high current Schottky rectifier module series

has been optimized for low reverse leakage at high tempera-

ture. The proprietary barrier technology allows for reliable

operation up to 175° C junction temperature. Typical applica-

tions are in switching power supplies, converters, free-

wheeling

diodes, and reverse battery protection.
