Hiiii...

I have a circuit using an IRF540 well within its current and voltage ratings.
The MOSFET failed. 54Ω drain-source and 5.1Ω drain-gate.

Would overheating result in a drain-gate short or was there some other problem that caused this?

Thanks!

I didn't find the right solution from the Internet.
