The input capacitance is 177 pF at 100 V drain-source, so the Miller plateau is short and the switching edges are clean with a well-laid-out gate loop. The threshold voltage is specified at 5 V maximum at 100 µA drain current, with a recommended drive voltage of 10 V for minimum on-resistance. This is a standard-threshold part — not logic-level — so ensure your gate driver swings to at least 10 V to get the rated Rds(on).
Temperature range and package — where it lives on the board
The junction temperature range is -55 to 150 °C, which covers industrial and many automotive under-hood environments. The base product number is STD5N80, so this is the K5 variant of the 800 V, 4 A DPAK family.
It is ROHS3 compliant.
