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.
