| Bulletin PD-2.369 rev. B 08/01 440CMQ030 SCHOTTKY RECTIFIER 440 Amp TO-244AB isolated Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM range IFSM @ tp = 5 s sine VF TJ @ 100Apk, TJ=125C (per leg) range Description/Features 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. 150 C TJ operation Center tap module - Isolated Base High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance Very low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability 440CMQ030 Units 440 30 27,000 0.41 A V A V - 55 to 150 C LUG TERMINAL ANODE 1 COMMON CATHODE LUG TERMINAL ANODE 3 2 ISOLATED BASE Modified JEDEC Outline TO-244AB Isolated Dimensions in millimeters and (inches) www.irf.com 1 440CMQ030 Bulletin PD-2.369 rev.
