Product details

The 190 mOhm maximum on-resistance at 13 V gate drive and 6.2 A Id targets hard-switching topologies like power-factor correction stages, flyback converters, and two-switch forward designs where 500 V blocking is needed and conduction loss matters.

The 190 mOhm Rds(on) at 13 V drive and 6.2 A Id sets the conduction loss floor. At 6 A load, expect roughly 7 W dissipation from the channel alone, which the 32 W package limit can handle with adequate heatsinking. The gate charge of 47.2 nC at 10 V is moderate — a standard gate-driver IC can switch it at 50–100 kHz without excessive drive loss. Input capacitance of 1137 pF at 100 V Vds keeps the Miller plateau manageable, so you are not forced into a high-current gate driver for moderate frequencies.

TO-220 Full Pack — rework and mounting notes

The PG-TO220-FP is a through-hole full-pack with the drain tab fully encapsulated. No exposed metal on the back means no mica washer or sil-pad needed — bolt it straight to the heatsink with a screw and a spring washer.

Frequently asked questions

What is the Rds(on) of IPA50R190CEXKSA2?

The maximum on-resistance is 190 mOhm at 13 V gate drive and 6.2 A drain current. This is the key spec for estimating conduction loss in your power stage.
