Schottky Rectifier, 2 x 10 A

20CTQ...S/20CTQ...-1

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

reliability

• Designed and qualified for Q101 level

DESCRIPTION

The 20CTQ.. 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.
