60 V, 2 A Schottky for automotive DC rails
The STPS2L60AY is a 60 V, 2 A Schottky rectifier in the DO-214AC (SMA) package, part of ST's Q Automotive series. It is designed for low-voltage, high-frequency rectification in automotive modules — think reverse-battery protection, freewheeling diodes on relay coils, or OR-ing diodes in a 12 V supply rail. The 600 mV forward voltage drop at 2 A keeps conduction losses manageable for a 2 A part, while the 100 µA reverse leakage at 60 V is typical for a 60 V Schottky — the leakage climbs with junction temperature, so the thermal design should account for it in a hot engine bay.
Junction temperature and switching speed
The fast-recovery speed qualifies it for switching frequencies above 200 mA, suitable for DC-DC converter output rectification and snubber clamping where recovery losses matter. In an SMA package, the thermal pad under the cathode is the primary heat path.
Active production, automotive grade, RoHS3
The base product number STPS2 covers a family of 2 A Schottkys in SMA with varying reverse voltages; the 60 V variant is the highest-voltage option in that current class.
