Its 630 mV forward voltage at 20 A keeps conduction losses manageable for a 20 A rail, and the fast recovery (< 500 ns above 200 mA) suits moderate-frequency rectification in switch-mode power supplies and freewheeling diodes. ## Parametric profile — what the ratings mean on a 20 A rail At 20 A forward current the 630 mV Vf produces 12.6 W of conduction loss — the TO-220 tab must be bolted to a heatsink sized for that dissipation at the ambient temperature. The 60 V reverse rating gives a 25 % derating margin on a 48 V bus, adequate for most non-automotive supplies. Reverse leakage is 85 µA at 60 V, which rises with junction temperature; the 150 °C maximum junction temperature sets the thermal trip point.","metaTitle":"STPS20SM60D Schottky Diode 60V 20A TO-220AC, Obsolete","metaDescription":"STPS20SM60D Schottky rectifier, 60V reverse, 20A average, 630mV Vf.
