At 15 A average the drop will be lower, but the 30 A point gives a realistic worst-case for thermal design. Junction temperature is rated to 175°C, so with good heatsinking this diode can handle sustained current in a cramped enclosure. ## Reverse leakage and switching speed Reverse leakage is 200 µA at 45 V — typical for a 45 V Schottky, but worth noting if your circuit idles hot; leakage doubles with temperature. The fast recovery rating (≤500 ns, >200 mA) means it handles the reverse-recovery transient cleanly in a 50/60 Hz rectifier or a lower-frequency SMPS output stage.","metaTitle":"STPS1545FP Schottky Diode, 45V 15A TO-220FPAC","metaDescription":"STPS1545FP Schottky diode, 45V reverse, 15A average, 840mV forward drop at 30A.
