Its 40 ns reverse recovery time (trr) is the parameter that determines switching losses in hard-switched topologies — a 40 ns trr keeps the recovery charge low enough for continuous-conduction-mode PFC stages and high-frequency rectification in the 50–100 kHz range. ## 1.7 V forward drop at 10 A — conduction loss budget That 1.7 V times the average current gives the conduction loss floor — 17 W at full load. The TO-220FPAC full-pack package isolates the tab electrically, so no insulating washer is needed against the heatsink, but the thermal path is through the full plastic body, which adds junction-to-case thermal resistance compared to a standard TO-220.","metaTitle":"STTH10R04FP Fast Recovery Diode, 400 V, 10 A, 40 ns trr","metaDescription":"STTH10R04FP fast recovery diode: 400 V reverse, 10 A average, 40 ns trr.
