DESCRIPTION
Single Schottky rectifier suited for switch mode
power supplies and high frequency DC to DC
converters.
SOD-123
Packadesin SOD-123,these devicseare intended
for use in low voltage, high frequency inverters,
freewheeling and polarIty protectionapplications.
Dueto thesmallsize ofthepackagethesedevices
fit GSMand PCMCIArequirements.
