Schottky Rectifier, 2 x 20 A

43CTQ...S, 43CTQ...-1

Vishay High Power Products

FEATURES

• 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

• Designed and qualified for AEC-Q101 level

DESCRIPTION

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, freewheeling diodes, and reverse battery

protection.
