SCHOTTKY RECTIFIER

18 Amp

I_F(AV)= 18Amp

V_R= 35 to 45V

Major Ratings and Characteristics

Description/Features

The 18TQ 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.
