It carries the base product number STPS160 and is part of the Automotive series. Key characteristics include a forward voltage drop of 670 mV at 1 A, a reverse leakage of 4 µA at the rated 60 V reverse voltage, and a junction temperature range spanning -40°C to 150°C. The fast recovery speed (≤500 ns at >200 mA) suits it for switching power supply rectification and freewheeling diode roles in automotive ECUs, body controllers, and DC-DC converter stages.
1 A continuous current at 60 V — sizing the power rail
The 670 mV forward drop at the rated 1 A load means about 670 mW dissipation at full current — within the SMA package's thermal capability when the PCB copper area is adequate. For continuous operation near 1 A, verify the junction temperature stays below 150°C using the thermal resistance from the datasheet's typical land pattern.
AEC-Q101 qualification for automotive deployment
The STPS160AY carries AEC-Q101 qualification, meaning it has undergone the stress tests required for automotive-grade discrete semiconductors: high-temperature reverse bias, temperature cycling, and humidity testing. This qualification is the baseline requirement for under-hood and passenger-compartment electronics in production vehicles.
DO-214AC SMA — footprint and reflow
Housed in the standard SMA package, the STPS160AY is a surface-mount device with a supplier device package of SMA (DO-214AC). The SMA footprint is widely used for 1 A-class rectifiers and shares pad compatibility with many industry-standard Schottky and ultrafast diodes. Standard reflow profiles for MSL 1-rated SMA devices apply.
