FEATURES AND BENEFITS

Single Schottky rectifier suited to Switched Mode

Power Supplies and high frequency DC to DC con-

verters.

Packaged in SMC, this device is especially in-

tended for use as an antiparallel diode on synchro-

nous rectification freewheel MOSFET’s at the

secondary of 3.3V SMPS and DC/DC units.
