On a 24 V bus the 45 V rating gives roughly 1.9× headroom for switching transients, which is comfortable for most industrial supplies. The 550 mV forward drop at 15 A means about 8.3 W per diode at full tilt; the TO-220 package with a heatsink is mandatory above a few amps continuous.","metaTitle":"STPS30L45CT Schottky Diode","metaDescription":"STMicroelectronics STPS30L45CT dual Schottky rectifier, 45V Vr, 15A per diode, 550mV Vf at 15A.
