SFFS816 March 2024 TMUX4051-Q1 , TMUX4052-Q1
This section provides functional safety failure in time (FIT) rates for the SOT-23-THIN package of the TMUX405x-Q1 based on two different industry-wide used reliability standards:
FIT IEC TR 62380 / ISO 26262 | FIT (Failures Per 109 Hours) |
---|---|
Total component FIT rate | 10 |
Die FIT rate | 5 |
Package FIT rate | 5 |
The failure rate and mission profile information in Table 2-5 comes from the reliability data handbook IEC TR 62380 / ISO 26262 part 11:
Table | Category | Reference FIT Rate | Reference Virtual TJ |
---|---|---|---|
5 | BICMOS ASICs Analog and Mixed =< 50V supply | 20 FIT | 55°C |
The reference FIT rate and reference virtual TJ (junction temperature) in Table 2-6 come from the Siemens Norm SN 29500-2 tables 1 through 5. Failure rates under operating conditions are calculated from the reference failure rate and virtual junction temperature using conversion information in SN 29500-2 section 4.
