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