The junction temperature limit is 150 °C, so the TO-247-3 case needs a heatsink for continuous operation above a few amps; the through-hole mounting lets you bolt it to a chassis or extruded aluminum sink. Reverse leakage at 45 V is 400 µA, which adds negligible standing loss in most designs. ## Switching speed and recovery The Schottky barrier inherently avoids stored-charge reverse recovery, so the speed rating reflects the junction capacitance rather than minority-carrier sweep-out. For flyback or forward-converter output stages running 50–100 kHz, the 500 ns ceiling is conservative; the actual recovery is typically much faster.","metaTitle":"STPS30L45CW Schottky Rectifier","metaDescription":"STPS30L45CW Schottky diode pair: 45V Vr, 15A per diode, 550mV Vf at 15A.
