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
DESCRIPTION
Dual center tap Schottky rectifier suited to
Switched Mode Power Supplies and high
frequency DC to DC converters.
Packaged in TO-220AB and D
