The Infineon IPA95R750P7XKSA1 is a 950 V N-channel MOSFET from the CoolMOS P7 series, built in a through-hole TO-220 Full Pack (PG-TO220-FP) package. The 950 V drain-source rating gives real margin in 380 V DC-link PFC stages and universal-input flyback converters where 800 V bus transients are common — you are not running the part at its ceiling.
The CoolMOS series is a current-generation high-voltage MOSFET family, so there is no imminent end-of-life or last-time-buy pressure.
Package and thermal handling — the Full Pack advantage
The TO-220 Full Pack (PG-TO220-FP) is the fully isolated variant of the standard TO-220. The metal tab is encapsulated, so no mounting insulator or thermal pad is needed between the device and the heatsink — a BOM simplification for high-voltage offline supplies where creepage and clearance are tight. Plan the heatsink accordingly.
