SCHOTTKY RECTIFIER

Amp

TO-203AB (DO-5)

Description/ Features

Major Ratings and Characteristics

The 85HQ 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.
