FEATURES AND BENEFITS
VERY LOW FORWARD VOLTAGE DR OP FOR LESS POWER DISSIPATION
OPTIMIZED CONDUCTION / REVERSE LOSSES TRADE-OFF WHICH MEANS THE HIGHEST EFFICIENCY IN THE APPLICA­TIONS
DESCRIPTION
Single Schottky rectifier suited to Switched Mode Power Supplies and high frequency DC to DC con­verters.
This device is especially intended for use as a rectifier at the secondary of 3.3V SMPS units.
