Schottky Rectifier, 2 x 10 A

20CTQ150S, 20CTQ150-1

Vishay High Power Products

FEATURES

• Center tap configuration

• Low forward voltage drop

• High frequency operation

• High purity, high temperature epoxy encapsulation for

enhanced mechanical strength and moisture resistance

• Guard ring for enhanced ruggedness and long term

reliability

• Designed for industrial level

DESCRIPTION

This center tap Schottky rectifier 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, converters, freewheeling diodes, and reverse

battery protection.
