FEATURES AND BENEFITS
n LOW COST DEVICE WITH LOW DROP FOR-
WARD VOLTAGE FOR LESS POWER
DISSIPATION AND REDUCED HEATSINK
n OPTIMIZED CONDUCTION/REVERSE LOSSES
TRADE-OFF WHICH LEADS TO THE
HIGHEST YIELD IN THE APPLICATIONS
DESCRIPTION
Single Schottky rectifier suited to Switched Mode
Power Supplies and high frequency DC to DC con-
verters.
Packaged in IPAK, this device is especially in-
tended for use as a Rectifier at the secondary of
3.3V SMPS or DC/DC units.
