ISO7320C: ISO7320C-Q1 - Reliability Data

Part Number: ISO7320C

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: ISO7320C-Q1

  • Hi David,

    Sorry that our MTBF tool is still down. I am told that we are working on getting it back online, but let me check in on that now. Unfortunately I do not believe there is another way for you to access this data. In the meantime, please feel free to ask about it on this forum and we'll try to respond as quickly as we can. Again our apologies that the tool is down. 

    ISO7320C-Q1

    MTBF: 2.48E+09

    FIT:0.4

    Best regards, 

    Dan

    Thank you for the fast response. I assume that the data are valid for 55°C and a confidence level of 60%. Can you approve?
  • In reply to David Beyeler:

    Hi David,
    Yes that is correct.
    Best regards,

  • In reply to Dan Kisling:

    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 Temperature

    * Activation energy

    * Test duration

    * Sample Size

    * Number of Fails

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

    Hey David,

    I understand. See below:
