Description/ Features
The MBR350, MBR360 axial leaded Schottky rectifier has
been optimized for very low forward voltage drop, with
moderate leakage. Typical applications are in switching
power supplies, converters, free-wheeling diodes, and
reverse battery protection.
Low profile, axial leaded outline
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
