TL431: Higher Total Ionizing Dose (TID)

TISL
Expert 4620 points
Part Number: TL431
Other Parts Discussed in Thread: TL1431, TL1431-SP

Dear E2E Support,

Our TL1431 QML-Q is specified with a maximum TID of 150 krad.

Did we performed tests at higher TID?

What would be the maximum TID tested on the TL1431 QML-Q and QML-V?

Regards,

    TISL,

    I'm not aware of tests performed at higher TID than what is specified as maximum. We spec maximum based on a range we can expect the device to behave as expected. Additionally, I think you are referring to the TL1431-SP, our highest rated part, which is QMLV qualified to only 100k Rad.

    Thanks,
    Abhinav.

    The mil grade QML-Q TL1431 is not specified to any radiation level.  We do not test, qualify or rate mil grade QML-Q parts for radiation.   The mil grade QML-Q parts will have differences from the space grade, radiation qualified parts and the space grade radiation test data cannot be applied to mil grade parts.

    The space grade QML-V part is TL1431-SP and it is qualified to 100 krad as shown in the datasheet.  Radiation lot acceptance testing (RLAT) is only performed to 100 krad.  We did do some teting to 150 krad, and the results are shown in the TID characterization report under the Tecnical documents tab in the TL431-SP product page.  We have not performed any testing higher than tha.
