3 A, 60 V Schottky in a flat SOD-128
The STPS360AF is a 60 V, 3 A Schottky rectifier from STMicroelectronics, housed in a low-profile SOD-128 flat-lead package. Its 610 mV forward voltage at 3 A keeps conduction losses low in power-supply secondary rectification, OR-ing diodes, and reverse-polarity protection circuits.
Junction rating and thermal headroom
Rated junction temperature spans -40°C to 175°C, which covers automotive under-hood and industrial power-supply hot spots. The 150 µA reverse leakage at 60 V is a typical Schottky trade-off — expect leakage to climb with temperature, so the thermal pad area on the PCB sets the real-world derating.
SOD-128 flat (ST's SOD128Flat supplier package) is a surface-mount, two-terminal outline with a large cathode tab for heat sinking. The flat leads reduce tombstoning risk during reflow and keep the mounted height low for dense boards.
The base product number is STPS360, so variants in different packages (e.g., STPS360B in DPAK) share the same die but differ in thermal performance.
