That speed is enough for a 100 kHz power-factor-correction boost stage or a hard-switched inverter output rectifier, where turn-off losses matter. At 80 A average and 600 V reverse voltage, the diode is sized for a 400 V DC bus with 200 V margin — typical in three-phase industrial rectifiers, battery chargers, and welding power supplies. ## 80 A average, 1.6 V forward drop — thermal budget The 80 A average rectified current (Io) is the headline thermal rating. Forward voltage is 1.6 V max at 80 A, so conduction loss at full load is about 128 W — that means a substantial heatsink, forced air, or both. The DO-247 through-hole package is designed for bolting to a heatsink; the junction is rated to 175°C max. Reverse leakage is 50 µA at 600 V, negligible for the thermal calculation. ## DO-247 through-hole — footprint and handling The DO-247-2 package has straight leads for through-hole mounting. It is a large tab package that needs a hole in the PCB or a separate heatsink bracket. Hand-solderable with a decent iron, but the tab carries the cathode — keep the heatsink electrically isolated or use an insulating pad. No moisture sensitivity level concern for through-hole parts, but the leads are tin-plated and solder fine with standard rosin flux.","metaTitle":"STTH8006W Fast Recovery Diode, 600V 80A DO-247, 105ns trr","metaDescription":"STTH8006W fast recovery diode from STMicroelectronics: 600V Vr, 80A average, 105ns trr, DO-247 through-hole.
