Bulletin PD-2.369 rev. B 08/01 440CMQ030 440 Amp SCHOTTKY RECTIFIER TO-244AB isolated Description/Features Major Ratings and Characteristics Characteristics 440CMQ030 Units The 440CMQ 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 150 °C junction temperature. Typical applications are in switching power supplies, converters, free-wheeling diodes, and reverse battery protection.
