Vishay High Power Products

FEATURES

• Center tap TO-220 package

• 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

DESCRIPTION

The 20CTQ...PbF 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, converters,

freewheeling diodes, and reverse battery protection.
