The junction is rated to 175°C maximum, and the 1.85 V forward drop at 8 A means the part dissipates about 15 W at full rated current, so a heatsink is mandatory for continuous operation. Reverse leakage at 600 V is 8 µA, negligible in the thermal budget. ST lists the STTH806DIRG as Active product status and ROHS3 compliant.","metaTitle":"STTH806DIRG Diode 600V 8A Fast Recovery TO-220AC Ins","metaDescription":"STTH806DIRG 600V 8A fast recovery diode, 55 ns trr, TO-220AC insulated package.
