Gate charge and input capacitance — driver selection matters
A weak driver will stretch switching edges and increase dissipation. Plan for a dedicated driver IC, not a microcontroller pin.

Frequently asked questions
What is the Rds(on) of AUIRFP4568-E?
Maximum on-resistance is 5.9 mOhm at 103 A drain current with 10 V gate drive.
Is AUIRFP4568-E RoHS compliant?
Yes, it is ROHS3 compliant.
What is the replacement for AUIRFP4568-E?
No direct replacement is listed. The IPD50R950CEAUMA1 is a 500 V, 4.3 A CoolMOS part in a different package and current class — not a functional substitute.
