650 V, 96 A automotive-class CoolMOS — what this part is
The Infineon IPW65R022CFD7AXKSA1 is an N-channel CoolMOS power MOSFET from the automotive-qualified CFD7 series. The AUTOMOTIVE_COOLMOS designation signals qualification for automotive-grade applications such as traction inverters, on-board chargers, and high-voltage DC-DC converters.
The gate charge of 234 nC at 10 V is substantial — this is not a small-signal FET. The driver stage needs to source several amperes peak to achieve the switching speeds the datasheet assumes. The input capacitance of 11659 pF at 400 V Vds confirms the gate drive must be designed for a high capacitive load. The 10 V drive voltage is the nominal operating point; the threshold voltage maximum is 4.5 V at 2.91 mA, so the device is not a logic-level part and will not fully enhance at 5 V gate drive.
Thermal and mechanical fit for the BOM
The maximum power dissipation is 446 W at the case. The TO-247-3 package requires a through-hole mounting process and a heatsink with a mounting hole; it is not a reflow part. The part is ROHS3 compliant.
