Description/ Features

The 8TQ...G 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, free-wheeling diodes, and re-

verse battery protection.

175° C TJ operation

High purity, high temperature epoxy encapsulation for

enhanced mechanical strength and moisture resistance

Low forward voltage drop

High frequency operation

Guard ring for enhanced ruggedness and long term

reliability
