The STMicroelectronics STPS10H60SFY is a 60 V, 10 A Schottky rectifier in the TO-277 (3-PowerDFN) surface-mount package, part of the automotive-grade STPS10 family.
The 10 A average rectified current (Io) covers alternator diodes, high-current relay coils, and motor-drive freewheeling paths. Forward voltage is 790 mV at the full 10 A rating. The 20 µA reverse leakage at 60 V is standard for this voltage class and junction size. The fast recovery spec (≤ 500 ns at > 200 mA) confirms this is a standard-speed Schottky.
The TO-277 (3-PowerDFN) package has an exposed pad for heat sinking. The -40°C to 175°C junction range covers cold-crank and under-hood soak conditions.
