Characteristics MBR1100 Units The MBR1100 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
