40CTQ045STRL - International Rectifier

SCHOTTKY RECTIFIER 40 Amp

Bulletin PD-20544 rev. C 12/01

www.irf.com

This center tap Schottky rectifier 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 configuration

Very low forward voltage drop

High purity, high temperature epoxy encapsulation for

enhanced mechanical strength and moisture resistance

High frequency operation

Guard ring for enhanced ruggedness and long term

reliability
