600 V, 8 A, 55 ns — the switching diode for PFC and SMPS outputs
It is a general-purpose, standard-technology part in the D2PAK (TO-263) surface-mount package — the same footprint used across the STTH806 family.
At 8 A forward current the maximum forward voltage is 1.85 V — that is the conduction-loss figure to budget in the thermal calculation. Reverse leakage is 8 µA at the 600 V blocking voltage, which is low enough to ignore in most designs but does double with junction temperature rise. The TO-263 package is a three-lead plus tab outline; the tab is the cathode, so the PCB copper pour under it doubles as the thermal path and the high-side rail.
ROHS3 compliance is confirmed.
