SCHOTTKY RECTIFIER

40 Amp

PD-20542 rev. B 11/99

www.irf.com

This center tap Schottky rectifier series has been optimized for

low reverse leakage at high temperature. The proprietary

barrier technology allows for reliable operation up to 175°C

junction temperature. Typical applications are in switching

power supplies, converters, free-wheeling diodes, and reverse

battery protection.

175° C T

operation

Center tap configuration

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
