Re: That must have been toasty
Commercial grade devices should operate between 0 and 70 for a long time. Multiple years.
When the junction temperature goes above 100 c the device moves through the lifetime bathtub. Performance to spec will be poor (fails). High temperature canork for a thousand hours (HTOL) the arrhenius equation will give an estimate of the lifetime.
Device functionality is not guaranteed above 70.
I just test the devices not qualify them.
