Description/Features

The 15CTQ center tap Schottky rectifier series has been

optimized for very low forward voltage drop, with moderate

leakage. The proprietary barrier technology allows for reli-

able 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 package

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
