Description
Single Schottky rectifier suited for switch mode
power supplies and high frequency DC to DC
converters.
Packaged in STmite flat, this device is intended
for use in low voltage, high frequency inverters,
free wheeling and polarity protection applications.
Due to the very small size of the package this
device fits battery powered equipment (cellular,
notebook, PDA’s, printers) as well as chargers
and PCMCIA cards.
