The metal tab is the common-cathode node; the two anode pins are the individual diode inputs. Heatsink mounting requires a thermal pad or grease — the junction-to-case thermal resistance is not listed here, but the 175°C Tj max and 10 A per leg define the derating curve for forced-air or convection-cooled designs. ## Fast recovery speed — Schottky switching edge Listed as Fast Recovery (≤500 ns, >200 mA Io), typical for a Schottky — the majority-carrier structure eliminates stored charge, so recovery time is negligible compared to a pn-junction diode at this voltage class.","metaTitle":"STPS20120CT Schottky Diode, 120V 10A Common Cathode TO-220","metaDescription":"STPS20120CT Schottky diode array, 120V reverse, 10A per diode, 920mV Vf at 10A.
