Major Ratings and Characteristics Description/Features

The MBR6045WT 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 150° C junction temperature. Typical applica-

tions are in switching power supplies, converters, free-wheel-

ing diodes, and reverse battery protection.

150° C TJ operation

Center tap TO-247 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

Dimensions in millimeters and inches
