(R) STPS0520Z SCHOTTKY RECTIFIERS MAIN PRODUCT CHARACTERISTICS IF(AV) VRRM VF (max) 0.5 A 20 V 0.32 V FEATURES AND BENEFITS s s s 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. Packaged in SOD-123, 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 GSM and PCMCIA requirements.
