Product details

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.

Frequently asked questions

What is the maximum continuous drain current of STF6N80K5?

Continuous drain current is 4.5 A at 25°C case temperature.

What package does STF6N80K5 come in?

The device is supplied in a TO-220FP full-pack through-hole package (TO-220-3 Full Pack). The moulded back is electrically isolated, so no separate insulating pad is needed when mounting to a heatsink.
