DS26F32MQML: Thermal Resistance: Junction to Case

Samuel Porter1

Part Number: DS26F32MQML

Hi TI,

In this part's data sheet the Junction to Case value is said to be found in MIL-STD-1835, however after scowering that document I could not find any reference to thermal values.

Do you guys have any suggestions or knowledge on the standard and what this part's value is?

Thanks,
Sam

    These values are listed in mil-std-1835.

    Mil std 1835 can be accessed here:

    The easiest way to determine the correct package identifier, is by checking the SMD drawing.

    In the SMD drawing each case outline letter is defined.

    For example the 5962-7802005M2A has outline letter 2 corresponding to CQCC1-N20

    This is listed in mil-std-1835 on page 20 showing a Theta Jc of 20 degrees C/W.

    Other packages are similarly listed.
