60 V, 5 A Schottky in a low-profile TO-277A package
The STPS5L60SF is a 60 V, 5 A Schottky rectifier from STMicroelectronics, housed in a TO-277A (SMPC) surface-mount package. It's part of the ECOPACK®2 series, which means it's fully RoHS-compliant and designed for lead-free soldering processes — no special handling for legacy tin-lead profiles. Rated for 5 A average rectified current at a maximum junction temperature of 150°C, this diode fits into low-voltage DC-DC converter outputs, OR-ing diodes in redundant power supplies, and freewheeling diodes in buck converters. The 60 V reverse voltage gives enough headroom for 48 V bus rails and 12 V automotive systems with load-dump transients.
Switching speed and leakage — the real design constraints
Listed as a fast recovery Schottky (≤500 ns, >200 mA), this part is not an ultrafast or SiC device — it's a standard Schottky with a low forward voltage drop. The switching speed is adequate for power supplies switching at 100–300 kHz, but above that the reverse recovery charge starts to dominate losses. Reverse leakage is specified at 470 µA at 60 V and 25°C. That figure climbs exponentially with junction temperature — at 125°C expect several milliamps. For standby or always-on circuits, factor this into the quiescent current budget; for continuous conduction, the leakage contributes to self-heating and must be included in the thermal calculation.
Active lifecycle and sourcing posture
The closest functional peer in the same package is the STPS5H100AF, a 100 V, 5 A Schottky. If your design needs more blocking margin (e.g., 48 V bus with 80 V transients), that part drops into the same footprint without a board spin. For the same 60 V rating but lower current, the STPS3L60S (3 A) shares the same package and pinout.
