650 V, 150 mOhm — the conduction-loss anchor for automotive power stages
That number drives the heatsink selection and the thermal interface budget.
AEC-Q101 and 150°C junction — what the automotive grade buys you
The 195.3 W maximum power dissipation at case temperature is a package-limited ceiling — the actual dissipation in a 105°C ambient under-hood environment will be lower, but the headroom is there for pulsed loads like solenoid drives and DC-DC pre-regulators.
Gate drive and switching — 86 nC at 10 V
The total gate charge is 86 nC at 10 V, with the drive voltage specified at 10 V for both minimum and maximum Rds(on). That means the gate driver must supply 10 V and source enough peak current to charge 2340 pF input capacitance (at 100 V drain) within the target switching interval. At 100 kHz, the average gate-drive current is 8.6 mA; the peak current depends on the driver's output resistance and the external gate resistor. The ±20 V maximum gate-source rating gives margin for ringing on long gate traces, but the 4.5 V maximum threshold at 900 µA drain means the device is fully off below 4.5 V — a 5 V logic-level drive will not fully enhance it.
