Junction temperature range and the thermal envelope
Derate the continuous drain current above 25 °C per the datasheet's normalised curve; at 100 °C case temperature the usable Id drops to roughly 7 A.
Gate drive and switching behaviour
The gate threshold voltage maximum is 4 V at 440 µA drain current, and the recommended drive voltage for the rated Rds(on) is 10 V. The 1670 pF input capacitance at 400 V drain-source is the capacitive load the driver sees at turn-on.
