Its 30 ns reverse recovery time places it in the fast-switching class needed for PFC boost stages, SMPS output rectification, and flyback snubbers where stored charge in the junction directly eats into efficiency. ## Forward drop and thermal budget Maximum forward voltage is 3.6 V at 8 A — a deliberate trade-off that keeps the die small and the recovery fast. At full rated current the conduction loss is about 29 W peak, which the TO-220AC insulated package must sink through the tab. Junction temperature is rated to 175 °C max, so the heatsink needs to hold the case temperature below about 150 °C at full load to stay inside the SOA.","metaTitle":"STTH806DTI Diode, 600V 8A, 30 ns trr, TO-220AC Insulated","metaDescription":"STTH806DTI ultrafast recovery diode, 600V 8A, 30 ns trr, TO-220AC insulated.
