500 V CoolMOS N-channel in a full-pack TO-220
The Infineon IPA50R250CPXKSA1 is a 500 V N-channel CoolMOS power MOSFET in the TO-220-3 Full Pack package.
At 7.8 A, I²R loss is roughly 15 W, which must be dissipated through the full-pack TO-220's thermal path. The full-pack construction has higher thermal resistance than a standard TO-220 because the backside tab is electrically isolated — the 33 W power dissipation rating (Tc) reflects this. For a 500 V rail, the 250 mOhm Rds(on) is a middle-ground figure; lower-resistance parts in the same voltage class exist but trade off gate charge and switching speed.
No pin-compatible second source or direct cross-reference is recorded in the available documentation.
Gate charge and input capacitance — switching considerations
These figures determine the gate-drive power requirement and switching transition times. In a hard-switched 500 V PFC or flyback converter, the combination of 1420 pF Ciss and 36 nC Qg is manageable with a standard MOSFET driver in the 1 A to 2 A peak-current class.
