700 V CoolMOS CE in a TO-220 Full-Pack — what you're working with
The IPAW70R950CEXKSA1: It comes in a TO-220 Full-Pack (fully isolated) package, so the tab is electrically isolated — no separate insulating washer or thermal pad needed when bolting it to a heatsink.
Gate drive and switching — light load on the driver
Gate charge is 15.3 nC at 10 V and input capacitance is 328 pF at 100 V drain bias. The 3.5 V maximum gate threshold at 150 µA requires 10 V drive for rated on-resistance.
Infineon lists the IPAW70R950CEXKSA1 as obsolete. For a new design, you need to select a current-production replacement. There is no factory lead time to manage; the supply picture is whatever the open market holds on the day you buy.
Thermal and mounting — the Full-Pack advantage
The PG-TO-220-3-FP package has an isolated tab, eliminating the need for a shoulder washer or insulating pad. Maximum power dissipation is 68 W at case temperature.
