Data Sheet

Failure Rate Prediction

The junction temperature of the device determines the failure rate of semiconductor devices. The relationship between ambient temperature and actual junction temperature is given by the following:

TJ °C = TA °C +
where

TA = ambient temperature in °C
= thermal resistance of junction-to-ambient in °C/Watt

PAVG = average power dissipated in Watt

The estimated MTBF and failure rate at temperatures lower than the actual stress temperature can be determined by using an Arrhenius model for temperature acceleration. Results of such calculations are shown in the table below using activation energy of 0.43V.
