Lifetime of a seminconductor is doubled for every 10 degC below Tj(max)

(1/2) > >>

Hi,
Ive heard the above rule, but can't find any official data on it, do you know of any?
Eg for example ,  in the case of a Power FET and diode in a 60W offline flyback SMPS.

I suspect it comes from, or is closely related to, the Arrhenius equation.

BravoV:
What is the baseline ? Say you can maintain it stable at 25 C, what will be the lifetime ?  :-//

it is worthwhile a copy & paste  :)


--- Quote ---A historically useful generalization supported by Arrhenius' equation is that, for many common chemical reactions at room temperature, the reaction rate doubles for every 10 degree Celsius increase in temperature
