Product details

The Infineon IPA50R140CPXK is a 500 V N-channel CoolMOS power MOSFET in a TO-220 Full Pack through-hole package. The 140 mOhm Rds(on) at 10 V gate drive is the figure that sets conduction loss in an offline flyback or PFC stage — at 14 A that's a 1.96 W dissipation just from Rds(on), plus switching losses from the 64 nC gate charge. The 23 A continuous drain current is package-limited by the TO-220 Full Pack's 34 W power dissipation ceiling, not the die itself; in a real supply you'll thermally limit well before hitting 23 A.

The 3.5 V gate threshold at 930 µA means a standard 10 V gate drive turns it on hard; at lower gate voltages the Rds(on) climbs — don't try to drive it from a 5 V logic rail without a proper gate driver.

Frequently asked questions

What is the maximum drain current of IPA50R140CPXK?

The continuous drain current is rated at 23 A at 25°C case temperature, limited by the TO-220 Full Pack package's 34 W power dissipation capability. In practice, the usable current depends on heatsinking and ambient temperature — the datasheet's thermal derating curve tells the real story for your application.
