To be honest, i am not satisfied with the ALF16N16W and ALF16P16W.

I have to make more measurements before i say more. But at higher level the starts to rise there vgs off region.

I have not seen it with Exicon ECX10N20 and ECX10P20.

It shows up as crossover into low loads. And when we lower the power level they cool of and the crossover disappears.

My first thought is that they cannot handle the power they are supposed to be handling. They are 250W package!!!!
