Its 55 ns reverse recovery time (trr) places it in the fast-recovery class (≤500 ns, >200 mA Io). ## 55 ns trr — switching loss anchor With a trr of 55 ns, the STTH806D limits reverse-recovery charge in continuous-current-mode PFC stages. At 8 A forward current and 1.85 V forward drop (Vf max at 8 A), conduction loss is roughly 14.8 W at full load — the junction temperature ceiling of 175°C sets the heatsink requirement. Reverse leakage is 8 µA at 600 V, a figure that rises with junction temperature and must be factored into standby-loss budgets. For existing designs, a last-time-buy or a parametric search for a TO-220AC fast-recovery diode with ≥600 V, ≥8 A, and ≤55 ns trr will identify a functional replacement.","metaTitle":"STTH806D Diode, 600V 8A Fast Recovery, TO-220AC","metaDescription":"STTH806D general purpose fast recovery diode, 600V 8A, 55ns trr, TO-220AC.
