The STF6N65M2: The TO-220FP (TO-220 Full Pack) has a fully molded, isolated tab — no exposed metal on the mounting surface.
It is ROHS3 compliant. For dual-sourcing, the closest pin-compatible alternative within the same MDmesh™ family would be a similar 650 V, 4 A N-channel in TO-220FP — verify Rds(on) and gate charge against your switching loss budget before substituting.
