Gate charge is 25 nC at 10 V, a moderate figure that suits medium-frequency hard-switching topologies like PFC boost stages, flyback converters, and two-switch forward converters in the 50–150 kHz range. Input capacitance measures 1020 pF at 100 V drain-source, which helps keep the drive current requirement manageable. This means Infineon has announced the end of production, and there is a finite window to place final orders. If this part is on your BOM, you need to evaluate your remaining demand, place a last-time-buy for the full lifetime requirement, or qualify a replacement before the order cutoff. The base product number is IPA50R350, which covers the CoolMOS CP series in this voltage and resistance class. A parametric search for 500 V, 350 mOhm, TO-220 Full Pack N-channel MOSFETs from other vendors may yield a cross-qualification candidate, but pinout and thermal performance must be verified against your layout. ## Thermal and drive considerations The TO-220 Full Pack's isolation layer adds thermal resistance compared to a standard TO-220, so the heatsink interface and mounting torque matter for staying within the SOA at high load. The gate-source absolute maximum is ±20 V, so a clamping zener on the gate is advisable if the drive supply can overshoot.","metaTitle":"Infineon IPA50R350CPXKSA1 CoolMOS N-Ch MOSFET, 500V, 10A","metaDescription":"Infineon IPA50R350CPXKSA1 CoolMOS N-channel MOSFET, 500V Vdss, 10A Id, 350mOhm Rds(on).
