SLLA502A October 2020 – December 2021 TCAN1042-Q1 , TCAN1042G-Q1 , TCAN1042GV-Q1 , TCAN1042H-Q1 , TCAN1042HG-Q1 , TCAN1042HGV-Q1 , TCAN1042HV-Q1 , TCAN1042V-Q1
This section provides Functional Safety Failure In Time (FIT) rates for TCAN1042-Q1 and TCAN1042V-Q1 (as well as the TCAN1042H-Q1, TCAN1042G-Q1, TCAN1042HV-Q1, TCAN1042GV-Q1, TCAN1042HG-Q1 and TCAN1042HGV-Q1) based on two different industry-wide used reliability standards:
| FIT IEC TR 62380 / ISO 26262 | FIT (Failures Per 109 Hours) 8-pin SOIC (D) | FIT (Failures Per 109 Hours) 8-pin VSON (DRB) |
|---|---|---|
| Total Component FIT Rate | 12 | 6 |
| Die FIT Rate | 4 | 2 |
| Package FIT Rate | 8 | 4 |
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 ASICs Analog & Mixed =<50V supply | 20 FIT | 55C |
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.
