30 ns trr — the switching-loss ceiling
The STTH802G is listed as Obsolete. Anyone designing a new board should look at the current STTH8xx family or a pin-compatible 8 A, 200 V ultrafast in D2PAK from another vendor; the 30 ns trr and 1.05 Vf are the targets to match.
D2PAK footprint — what the tab carries
The package is D2PAK (TO-263-3, two leads plus tab). The exposed copper tab is the cathode and the primary thermal path.
