Product details

The STF35N65DM2: N-channel 650 V MOSFET in the MDmesh DM2 series, rated 32 A continuous drain at 25 °C and 110 mOhm Rds(on) at 16 A, 10 V gate drive.

Gate charge and switching — 56.3 nC at 10 V

Gate charge is 56.3 nC at 10 V drive. Input capacitance is 2540 pF at 100 V drain bias.

Thermal and package — 40 W dissipation in a fully isolated tab

The TO-220FP (full-pack) case limits power dissipation to 40 W at case temperature, about half what a standard TO-220 with a metal tab can handle. That 40 W ceiling is the hard constraint for the thermal design: at 16 A and 110 mOhm, conduction loss alone is 28 W, leaving little headroom for switching loss. The isolated tab is a real advantage in production—no mica washer or thermal pad needed, which simplifies assembly and reduces thermal resistance to the heatsink.

Frequently asked questions

Can STF35N65DM2 be used as a replacement for STF30N65DM2?

The STF35N65DM2 is a higher-current variant compared to the STF30N65DM2, with a 32 A continuous drain rating versus a lower current rating. Both are 650 V N-channel MOSFETs in the same TO-220FP package, so the STF35N65DM2 can serve as a drop-in replacement if the circuit's current and thermal margins accommodate the higher rating. Verify gate charge and switching performance in your specific topology before committing.
