SCHOTTKY RECTIFIERS
STPS0530ZDecember 2002-Ed:1A
SCHOTTKY RECTIFIERS VERY SMALL CONDUCTION LOSSES NEGLIGIBLE SWITCHING LOSSES EXTREMELY FAST SWITCHING
FEATURES AND BENEFITSSingle Schottky rectifier suited for switch mode
power supplies and high frequency DCto DC
converters.
Packagedin SOD-123, this deviceis intendedfor
usein low voltage, high frequency inverters, free
wheeling and polarity protection applications. Due the small sizeof the package this device fits
GSM and PCMCIA requirements.
