STPS6x0CSFY Automotive Power Schottky Rectifiers STMicroelectronics STPS630CSFY, STPS640CSFY, and STPS660CSFY Automotive Power Schottky Rectifiers are designed for applications requiring an optimized VF and leakage current characteristics. These 30V, 40V, and 60V dual 3A diodes are also ideal for use in secondary rectification functions, such as DC to DC converters and freewheeling functions. The STPS630CSFY, STPS640CSFY, and STPS660CSFY Power Schottky Rectifiers offer low losses, low forward and reverse recovery time, high surge current capability, and a high maximum junction temperature.
