SCHOTTKY RECTIFIER

240 Amp

D-67

Major Ratings and Characteristics

Description/Features

The 243NQ high current Schottky rectifier module series has

been optimized for low reverse leakage at high temperature.

The proprietary barrier technology allows for reliable opera-

tion up to 175° C junction temperature. Typical applications

are in switching power supplies, converters, free-wheeling

diodes, and reverse battery protection.
