The IPAN70R450P7SXKSA1: Housed in a TO-220-3 Full Pack (PG-TO220-FP) — a fully isolated through-hole package. The 10 A continuous drain current and 22.7 W power dissipation suit it for medium-power offline switching applications where the 700 V blocking voltage provides margin for universal AC input rectified rails.
Gate charge and switching — what the 13.1 nC figure tells you
It means the gate driver does not need to supply a large current pulse to switch the device — a standard 1 A to 2 A gate driver IC can handle turn-on and turn-off transitions in the tens of nanoseconds. The 424 pF input capacitance at 400 V drain-source confirms the switching node capacitance is low enough for hard-switched topologies running at frequencies up to 100 kHz or so, though the full switching loss calculation depends on the specific operating point and gate drive strength. For high-frequency resonant converters, the low Qg helps keep circulating energy manageable.
Temperature range and thermal design
At 150°C junction, the Rds(on) will approximately double from the 25°C value, so conduction loss budgeting should use the hot resistance from the datasheet's typical curve.
