Its 30 ns reverse recovery time (trr) is the spec that separates it from slower 200 ns+ recovery diodes — in a continuous-conduction-mode PFC or a 100 kHz+ forward converter, that 30 ns trr keeps the reverse-recovery charge low enough that the MOSFET doesn't see a current spike at turn-on. The forward voltage drop is 1.05 V at the full 8 A rating, which sets the conduction loss budget for the heatsink calculation. ## Thermal and leakage — the operating envelope Junction temperature maxes out at 175°C, which gives headroom for cramped power supplies where the diode shares a heatsink with a hot MOSFET. Reverse leakage is 6 µA at the 200 V rated voltage — low enough that standby losses in a 200 V rail are negligible. The TO-220AC package (through-hole, TO-220-2 outline) is the standard power tab package; the metal tab is the cathode, so the heatsink interface needs an insulating pad if the heatsink is chassis-ground. ST lists the STTH802D as Active product status.","metaTitle":"STTH802D Fast Recovery Diode, 200V 8A, 30ns trr, TO-220AC","metaDescription":"STTH802D 200V 8A fast recovery diode with 30ns trr in TO-220AC package.
