Original question:

ISO7320C: ISO7320C-Q1 - Reliability Data

ISO7342C: ISO7342CQDWRQ1 - Reliability Data

Part Number: ISO7342C

The http://www.ti.com/quality/docs/estimator.tsp does currently not provide any data about the Digital Isolators. I notice that behavior already in the past and sometime later (few month) the data were available again. Is there a data base available where I can check the values independent of the MTBF estimator?

Currently the device of  interest is: ISO7342CQDWRQ1

    Hi David,

    Unfortunately we are still having issues with our online reliability tool (the irony is not lost on me). For the time being please bring your reliability questions to E2E and we will be happy to manually look up the information for you.

    Part number MTBF FIT Usage temp (°C) Conf level (%) Activation energy (eV) Test temp (°C)
    ISO7342CQDWRQ1 2.48E+09 0.4 55 60 0.7 125

    Please let me know if you have any questions. 

    Best regards, 

    Dan

    Because I have to calculate the FIT Rate for 30°C and 90% confidence, I need additional Information about how the 0.4 FIT has been tested.

    * Test duration

    * Sample Size

    * Number of Fails

    This are the MTBF/FIT supporting data usually provided by the MTBF estimator.

    (could you provide the same table as in: e2e.ti.com/.../684390 ?)

    Hi David,

    I should have recognized your username! I'll try to remember next time you ask to give you all of the numbers up front.
