SCHOTTKY RECTIFIER
180 Amp
Major Ratings and Characteristics
Description/Features
The 181NQ high current Schottky rectifier module series has
beenoptimizedforverylowforwardvoltagedrop,withmoderate
leakage. 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.
