MTBF/FIT Reliability Data for STM32H743VIT6

[Opampfanatic6367]

Hi,

I am trying to calculate the MTBF (mean time between failures) value for the STM32H743VIT6 module. Please suggest any techniques for the same. I am currently using the Qjc (Junction to Case Thermal Resistance) and Pd (Power Dissipation) values to calculate the same.

Please provide the Qjc value for STM32H743VIT6 at 35 and 50 degrees Celsius or suggest another appropriate method to calculate the MTBF value for the same.

Thanks,

OF
