FEATURES AND BENEFITS
VERY LOW FORWARD VOLTAGE DROP FOR
LESS POWER DISSIPATION AND REDUCED
HEATSINK
OPTIMIZED CONDUCTION/REVERSE LOSSES
TRADE-OFF WHICH MEANS THE HIGHEST
EFFICIENCY IN THE APPLICATIONS
HIGH POWER SURFACE MOUNT MINIATURE
PACKAGE
AVALANCHE RATED
DESCRIPTION
Single Schottky rectifier suited to Switched Mode
Power Supplies and high frequency DC to DC con-
verters.
This device is especially intended for use as a Rec-
tifier at the secondary of 3.3V SMPS units.
