STPS0540Z / STPS0560Z SCHOTTKY RECTIFIER MAIN PRODUCT CHARACTERISTICS I 0.5 A F(AV) V 40 / 60V RRM V (max) 0.40 / 0.50V F FEATURES AND BENEFITS n Very small conduction losses n Negligible switching losses n Extremely fast switching DESCRIPTION Single Schottky rectifier suited for switch mode power supplies and high frequency DC to DC converters. SOD-123 Packages in SOD-123, these devices 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.
