At 1.8 A Id the 650 mOhm maximum on-resistance produces about 2.1 W conduction loss at the top of the temperature range — a number to feed into the thermal budget against the 27.2 W power dissipation limit at the case. Gate charge is 15 nC at 10 V, which is modest for a 500 V device and keeps the driver burden low in medium-frequency hard-switching designs. Input capacitance of 342 pF at 100 V Vds is a figure that governs switching speed and driver sizing — lower capacitance means faster edges and less cross-conduction loss, but also tighter layout to keep ringing under control.

Frequently asked questions
What replaces IPA50R650CEXKSA2?
No official replacement order code is recorded on this listing. A replacement would need to match the 500 V Vdss, 650 mOhm max Rds(on), 4.6 A Id rating, and the TO-220 Full Pack package. A same-series CoolMOS CE part with similar ratings may be a candidate, but pin compatibility and electrical fit must be verified against the original datasheet.
What is the Rds(on) of IPA50R650CEXKSA2?
The maximum on-resistance is 650 mOhm at 1.8 A drain current with a 13 V gate drive. This is the worst-case value across operating temperature; typical values are lower.
