STPS0540Z / STPS0560Z SCHOTTKY RECTIFIER PRELIMINARY DATASHEET MAIN PRODUCT CHARACTERISTICS IF(AV) 0.5 A VRRM 40 / 60 V VF (max) 0.40 / 0.50 V FEATURES AND BENEFITS VERY SMALL CONDUCTION LOSSES NEGLIGIBLE SWITCHING LOSSES EXTREMELY FAST SWITCHING DESCRIPTION Single Schottky rectifier suited for switch mode power supplies and high frequency DC to DC converters. Packades in SOD-123, these devicse are intended for use in low voltage, high frequency inverters, free wheeling and polarIty protection applications. Due to the small size of the package these devices fit GSM and PCMCIA requirements.
