Why did it break?
Was it below spec?
Or was it driven beyond spec?

Maybe you need to consider how to make it reliable before deciding on the specification of the replacement.

Thanks AndrewT ;)

I don't know why it was broken because I recovered the power supply.

But i think that's the dust in the power supply blow the n-mos :xeye:

so do you know "with the datasheet " if it was possible to replace the original N-mos fqpf5n50c with one of theses parts IRFBC40 or STP3NC60FP

thanks a lot :)
