STMicroelectronics lists the STPS1545DY as obsolete. ## Parametric profile for the BOM The 200 µA reverse leakage at 45 V is specified at 25°C; leakage rises with junction temperature, so thermal margin matters in high-temperature automotive environments. The fast recovery characteristic (≤500 ns, >200 mA) is typical for a Schottky and suits switching power supply output rectification and freewheeling diode roles. ## Package and qualification Housed in a TO-220AC through-hole package (TO-220-2), the STPS1545DY is suitable for board-level mounting with a heatsink. The AEC-Q101 qualification confirms it meets automotive stress and reliability requirements, including extended temperature cycling and high-temperature reverse bias testing.","metaTitle":"STPS1545DY Schottky Diode, 45V 15A, AEC-Q101, TO-220AC","metaDescription":"STPS1545DY automotive Schottky rectifier, 45V reverse, 15A average, 570mV Vf at 15A.
