Bulletin PD-2.282 rev. C 07/01 440CNQ030 440 Amp SCHOTTKY RECTIFIER Description/Features Major Ratings and Characteristics Characteristics 440CNQ... Units The 440CNQ030 center tap, high current, Schottky rectifier module 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, welding and reverse battery protection.
