Automotive-grade Schottky in an SMC footprint
The STPS5L60SY is an STMicroelectronics Q Automotive series Schottky rectifier rated for 60 V reverse and 5 A average forward current, housed in a DO-214AB (SMC) surface-mount package. The Automotive grade qualifies it for under-hood and chassis-domain power stages where AEC-Q101 screening is a BOM requirement.
Forward drop and conduction loss at 5 A
Maximum forward voltage is 520 mV at 5 A. The 220 µA reverse leakage at 60 V is the standby power penalty; expect leakage to increase with junction temperature, so the thermal budget should account for the self-heating contribution from reverse bias in high-temperature soak conditions.
Junction temperature range and thermal design
The 150°C upper limit is the die-attach and wire-bond reliability boundary for the SMC package; derate the forward current above 100°C per the datasheet curve to stay within the SOA.
