I found this, I am sure most of you already have this info, but for those that do not.. Nice explanation on how they rate their current handling on MosFets.
I find it useful when you see absurd spec's on some of these huge current quotes on small parts.

My oh my! IRC should read and heed!!!
IR?
Still, the last method gets exciting. 50% lethal rating for datasheet?
Sounds like John L. territory :)

No- it means the final published IDM is 50% or less of actual QA sampling measurements on the product line, which is a destructive test in this case. See
I don't know how I should respond to that? I posted it out of common courtesy, in hopes that maybe it would be beneficial to some one?
I remember a slew of posts dating back some months ago with controversial specifications for Power MosFets from various venders with absurd Ids ratings in small packages. Knowing how engineers come up with these figures would make it most beneficial when implementing them in a project.
If you feel my efforts are wasted, just say so, I won't bother to post any more for the group.

I think that reference is excellent and very useful. Kills a lot of IR boasts as seen in their "data sheets".
It is an appropriate post IMHO.
If you look at some of the honest manufacturers' specs, they will give ludicrous specs on Id and then (in very small letters below) say that the package limits are lower.
This is a very appropriate flag.
Cheers, John
