2.3 SC70 and SON Packages

This section provides Functional Safety Failure In Time (FIT) rates for SC70 and SON packages of TXU0101-Q1 based on industry-wide used reliability standards:

  • Table 2-3 provides FIT rates based on IEC TR 62380 / ISO 26262 part 11
Table 2-3 Component Failure Rates per Siemens Norm SN 29500-2
Table Category Reference FIT Rate Reference Virtual TJ
5 CMOS Analog switch, Bus Interface 8 FIT 55°C

The Reference FIT Rate and Reference Virtual TJ (junction temperature) in Table 2-3 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.
