The MBRS140TRPbF surface-mount Schottky rectifier has been
designed for applications requiring low forward drop and very small
foot prints on PC boards. Typical applications are in disk drives,
switching power supplies, converters, free-wheeling diodes, battery charging, and reverse battery protection.
Small foot print, surface mountable
Low forward voltage drop
High frequency operation
Guard ring for enhanced ruggedness and long term
reliability
Lead-Free ("PbF" suffix)
