Web(2) Mean Time To Failure (MTTF) is often used interchangeability with Mean Time Before Failure (MTBF). The difference is in a repairable MTBF and non-repairable failure MTTF. The assumption here is that the semiconductor is not repairable but, potentially, that the system could be de-soldered and replaced making the system repairable.

WebTo calculate the MTTF d from B 10d, the following relationship must be taken into account: MTTF d = B10 d /0.1*n op. Where n op represents the number of operations the component performs in a year. B 10 and B 10d are generally provided by the manufacturer; if these data are not available, the values provided by the standard can be used instead. WebMTTF: Mean time to failure describes the expected time to failure for a non-repairable system. For example, assume you tested 3 identical systems starting from time 0 until all of them failed. The first system failed at 10 hours, the second failed at 12 hours and the third failed at 13 hours. The MTTF is the average of the three failure times ...

Mean Time to Dangerous Failure. In a safety system MTTFD is the portion of failure modes that can lead to failures that may result in hazards to personnel, environment or equipment. MTTFD is critical to the determination of the performance level of a safety system. ISO 13849 defines three levels of MTTFD: ISO 13849 prescribes three methods to determine the MTTFD of a safety channel: Web\$\begingroup\$ I agree with Barry.
