Schottky Rectifier, 2 x 20 A

42CTQ030S/42CTQ030-1

Vishay High Power Products

FEATURES

• Center tap configuration

• Very low forward voltage drop

• High frequency operation

• Guard ring for enhanced ruggedness and long term

reliability

• High purity, high temperature epoxy encapsulation for

enhanced mechanical strength and moisture resistance

• Designed and qualified for Q101 level

DESCRIPTION

This center tap Schottky rectifier module 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, freewheeling

diodes, and reverse battery protection.
