   The reliability test duration assures the device's adequate lifetime requirement. For example, with an activation energy of 0.7 eV, 125 °C stress temperature and 55 °C use temperature, the acceleration factor (Arrhenius equation) is 78.6. This means that 1,000 hours' stress duration is equivalent to 9 years of use.
