FEATURES AND BENEFITS
VERY LOW FORWARD VOLTAGE DROP FOR
LESS POWER DISSIPATION
OPTIMIZED CONDUCTION/REVERSE LOSSES
TRADE-OFF WHICH MEANS THE HIGHEST
EFFICIENCY IN THE APPLICATIONS
HIGH POWER SURFACE MOUNT MINIATURE
PACKAGE
DESCRIPTION
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.
