Description/Features
The MBRS190TR, MBRS1100TR 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
