Description/ Features

The MBR16.. 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 bat-

tery protection.

150° C TJ operation

High purity, high temperature epoxy encapsulation for

enhanced mechanical strength and moisture resistance

Low forward voltage drop

High frequency operation

Guard ring for enhanced ruggedness and long term

reliability
