The confidence level is established based on the chi-square distribution. [2] Failure rate (%/1K Hours) is 1/MTBF x 105, assuming the failures are exponentially distributed. [3] Data generated based on 55°C, 20mA and θJA = 780°C/W Example of Failure Rate Calculation Assume a device operating 8 hours/day, 5 days/week. The utilization factor, given 168hours/week is: (8hous/day) x (5 days/week) / (168 hours/week) = 0.25 The point failure rate per year (8760 hours) at 75 °C ambient temperature is: (1.091% / 1K hours) x 0.25 x (8760 hours/year) = 2.39% per year Similarly, 90% confidence level failure rate per year at 75 °C: (2.74% / 1K hours) x 0.25 x (8760 hours/year) = 6.00% per year. |
