47CTQ020PbF

40 Amp

SCHOTTKY RECTIFIER

I_F(AV)= 40Amp

V_R= 20V

Description/ Features

Major Ratings and Characteristics

This center tap Schottky rectifier has been optimized for

ultra low forward voltage drop specifically for 3.3V output

power supplies. The proprietary barrier technology allows

for reliable operation up to 150 °C junction temperature.

Typical applications are in parallel switching power supplies,

converters, reverse battery protection, and redundant power

subsystems.
