ISO7741-Q1: Reliability Data for Isolators

Part Number: ISO7741-Q1

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 devices of  interest are:

  • Hi David,

    Currently the MTBF estimator doesn't support isolator hence this data has to be requested manually. Please find below the MTBF data for the devices you have requested, thanks.

    1. ISO7741-Q1
    MTBF = 3.12 x 10^9 hours.

    2. ISOW7843
    Let me come back to you on this.

    What are the conditions: 55°C and 60% confidence level?

    Hi David,

    MTBF for ISOW7843 is going to be same as ISO7741-Q1. Hence,

    1. ISO7741-Q1
    MTBF = 3.12 x 10^9 hours

    2. ISOW7843
    MTBF = 3.12 x 10^9 hours

    Still open is the question about the conditions: 60% confidence level and 55°C?
  • In reply to David Beyeler:

    Hi David,

    Yes, the usage temperature is 55°C and confidence level is 60%.

    Thanks,
