Characteristics 30CTQ Units

Major Ratings and Characteristics Description/Features

The 30CTQ... center tap Schottky rectifier has been optimized

for very low forward voltage drop, with moderate leakage. 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 reverse battery protection.

175° C TJ operation

Center tap TO-220 package

High purity, high temperature epoxy encapsulation for

enhanced mechanical strength and moisture resistance

Very low forward voltage drop

High frequency operation

Guard ring for enhanced ruggedness and long term

reliability
