Product details

650 V N-channel MOSFET for automotive traction and DC-DC stages

The STW68N65DM6-4AG: AEC-Q101 qualified for automotive applications.

Gate charge and switching loss budget

Total gate charge is 118 nC at 10 V gate drive. Input capacitance Ciss is 5900 pF at 100 V drain-source bias. This value, together with the gate resistance in the drive loop, determines the turn-on and turn-off delay — relevant for dead-time tuning in half-bridge topologies.

Package and thermal design

The TO-247-4 package adds a Kelvin-source pin (the fourth pin) that separates the gate-drive return from the power current path, reducing the voltage drop in the gate loop caused by source inductance. This lowers the risk of gate ringing at high di/dt. Maximum power dissipation is 480 W at the case, but the practical dissipation is set by the junction-to-case thermal resistance and the heatsink's ability to pull heat away. The operating junction temperature range is -55 °C to 150 °C.

Frequently asked questions

What is the difference between STW68N65DM6-4AG and STW68N65DM6?

The -4AG suffix indicates the TO-247-4 package with a Kelvin-source pin (four leads) and AEC-Q101 automotive qualification. The base STW68N65DM6 uses the standard three-pin TO-247 package and lacks the automotive-grade screening. Electrically the die is the same MDmesh™ generation, but the pinout differs — the fourth pin is the source Kelvin connection, not a drain or gate.
