DESCRIPTION

The 25CTQ...PbF center tap Schottky rectifier 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, freewheeling diodes, and reverse battery

protection.
