650 V N-channel in a 4-lead TO-247
The TO-247-4 package adds a Kelvin source pin that separates the gate-drive return from the high-current power path. This reduces common-source inductance in the gate loop, which translates to cleaner switching waveforms and lower turn-off losses in hard-switched topologies.
Gate charge and switching budget
Total gate charge is 204 nC at 10 V, with an input capacitance of 8825 pF at 100 V drain-source. The gate-driver must supply this charge each switching cycle — at 100 kHz the average gate-drive current is about 20 mA, well within a standard driver's capability, but the peak current during the Miller plateau determines the switching speed. The 450 W maximum power dissipation at case temperature is a package-limited rating; real-world dissipation is set by the junction-to-case thermal impedance and the heatsink's ability to hold the case below 150 °C.
