The failure rate is located in the poduct folder on the web page under Quality and reliability data.

TI Home > Support > Quality & Eco-Info > Reliability Data > Reliability Estimator

Reliability Data: Reliability Estimator Results

The following failure rates are summarized by technology and mapped to the associated material part numbers. The failure rates are highly dependent on the number of units tested, therefore, it is not recommended to compare failure rates.

Chris, do you have any data on how the TL1431 may fail when it does fail? Open circuit, short, no data?

Thanks,

Wade

We do not do any destuctive type testing. Normal mode of failure from EOS is fuse open. However it can aslo short so we cannot guarrantee anything.
