Schottky Rectifier, 8 A

8TQ...S Series

Vishay High Power Products

FEATURES

• 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 8TQ...S 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.
