Temperature grade and environment
The IPP60R280CFD7XKSA1: The 52 W maximum power dissipation at case temperature assumes an infinite heatsink; in practice the TO-220 tab must be bolted to a thermal pad or heat spreader sized for the application's ambient and airflow. The 807 pF input capacitance at 400 V drain is low enough that the gate driver's output impedance, not the MOSFET's Ciss, typically sets the switching edge rate.
Sourcing and compliance
The laser-etched marking on the TO-220 body should trace cleanly to Infineon's factory output — any lot with a font mismatch or sanded surface warrants decap inspection.
