The 181NQ high current Schottky rectifier module series has

been optimized for very low forward voltage drop, with moderate

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.
