MBRB15..CTPbF MBR15..CT-1PbF

Description/ Features

The MBR15.. 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 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
