The STPS2L60UF is a 60 V, 2 A Schottky rectifier in a low-profile SMBflat package. The 60 V reverse voltage covers 12 V, 24 V, and 48 V rails with margin; the 2 A average forward current suits secondary-side rectification, freewheeling diodes, and polarity protection in power supplies up to about 50 W. At lower loads the Vf drops, which helps keep junction temperature in check in lightly loaded designs.
Package and rework — SMBflat under the hot air
The SMBflat (DO-221AA) package is a low-profile surface-mount body with flat leads — no J-bend, no gull-wing. That flat lead sits flush on the pad, which makes solder-paste inspection straightforward and rework predictable. The package body is small enough that a standard hot-air nozzle at 350 °C will lift it cleanly without cooking the adjacent passives, provided the board has a thermal relief on the cathode pad. The junction temperature ceiling is 150 °C maximum. In a 2 A continuous application at 85 °C ambient, the thermal budget is tight — the SMBflat's junction-to-ambient thermal resistance means the copper pad area on the PCB sets the real current limit. A 1 oz copper pour of at least 300 mm² under the cathode tab keeps the junction below 125 °C at full load.
ROHS3 compliance is confirmed, so this part drops into a RoHS BOM without an exemption review.
