Description/ Features

This center tap Schottky rectifier has been optimized for low

reverse leakage at high temperature. The proprietary barrier

technology allows for reliable operation up to 150° C junction

temperature. Typical applications are in switching power

supplies, converters, free-wheeling diodes, and reverse

battery protection.

150° C TJ operation

Center tap TO-220 and D2Pak packages

Low forward voltage drop

High purity, high temperature epoxy encapsulation for

enhanced mechanical strength and moisture resistance

High frequency operation

Guard ring for enhanced ruggedness and long term

reliability
