SLLA525A October 2020 – April 2021 TCAN1043-Q1 , TCAN1043G-Q1 , TCAN1043H-Q1 , TCAN1043HG-Q1
This section provides Functional Safety Failure In Time (FIT) rates for TCAN1043-Q1 (as well as TCAN1043G-Q1, TCAN1043H-Q1, and TCAN1043HG-Q1) based on two different industry-wide used reliability standards:
| FIT IEC TR 62380 / ISO 26262 | FIT (Failures Per 109 Hours) 14-pin SOIC (D) | FIT (Failures Per 109 Hours) 14-pin VSON (DMT) |
|---|---|---|
| Total Component FIT Rate | 21 | 9 |
| Die FIT Rate | 3 | 3 |
| Package FIT Rate | 18 | 6 |
The failure rate and mission profile information in Table 2-1 comes from the Reliability data handbook IEC TR 62380 / ISO 26262 part 11:
| Table | Category | Reference FIT Rate | Reference Virtual TJ |
|---|---|---|---|
| 5 | CMOS,
BICMOS Digital, analog / mixed | 20 FIT | 55°C |
The Reference FIT Rate and Reference Virtual TJ (junction temperature) in Table 2-2 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.
