800 V N-channel in a full-pack through-hole
Maximum on-resistance is 1.6 Ohm at 2 A drain current with 10 V gate drive. At 4.5 A the conduction loss hits about 32 W at 25°C junction — but the TO-220FP package is rated for 25 W total dissipation, so you need to stay below the full current in a real thermal environment. Gate charge is 13 nC at 10 V, which keeps the drive current modest even at switching frequencies above 100 kHz. A typical gate driver delivering 1 A peak can charge the gate in about 13 ns, though the practical switching speed is limited by the miller plateau and the 270 pF input capacitance at 100 V drain bias.
