8TQ080SPbF, 8TQ100SPbF
Vishay High Power Products
FEATURES
• 175 °C TJ operation
• 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
• Compliant to RoHS directive 2002/95/EC

DESCRIPTION
The 8TQ... 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.
