The TO-220AC package (TO-220-2 outline) keeps the thermal path through the tab straightforward for a clip or screw mount. ## Forward drop at full load Maximum forward voltage is 1.3 V at 8 A, which at full rated current puts conduction loss near 10.4 W before switching losses are added. At lighter loads the Vf drops, so average dissipation in a discontinuous-mode PFC is lower than the 8 A continuous figure suggests. ## Leakage at rated voltage It does confirm the die quality — a leaky junction at rated voltage would show up here first. The 600 V rating leaves margin for 400 V bus applications (PFC output, inverter DC link) where transients can ring above the nominal rail.","metaTitle":"STTH8L06D 600V 8A Ultrafast Diode, 105ns trr, TO-220AC","metaDescription":"STTH8L06D ultrafast recovery diode from STMicroelectronics: 600V, 8A, 105ns trr in TO-220AC.
