Hi,
When it comes to lifetime calculation I am always confuse.
I have this thermal operating profile as below:-
Tj = 110C (operating hours = 400hrs)
Tj = 105C (operating hours = 1200hrs)
Tj = 100C (operating hours = 1650hrs)
Tj = 95C (operating hours = 2200hrs)
Tj = 90C (operating hours = 1520hrs)
Tj = 85C (operating hours = 73hrs)
Assuming available stress condition is at 125C at 1000hrs with typical voltage at 1V
Can the above profile exceed the lifetime of 10 years?
In terms of lifetime calculation, should we be calculating both temperature & voltage acceleration or just temperature acceleration alone as we only have the thermal operating profile?
Hope to get the answer ASAP.
Thanks in advance.
