LM119QML: LM119QMLV (5962R9679802VHA) pin base material

Bruno Simard67
Prodigy 230 points
Part Number: LM119QML

Tool/software:

Hello,

I am seeking information on the pin base material for the LM119QML-V. This information is needed to estimate the thermal conductivity of the IC pins.

Also can you indicate where I can find this kind of information typically. Since I did not find anythink into DSCC specsheet

Thank you

Regards

Bruno

    Hello Bruno,

    5962R9679802VHA is equivalent to LM119WRLQMLV

    The Material Content page will contain a section about the leadframe and the Lead Frame Plating plating:

     https://www.ti.com/quality-reliability-packaging-download/report?opn=5962R9679802VHA

    Leadframe is copper/nickel (Alloy 42) and the plating is 63/37 SnPb.

    Normally the thermal information is in the datasheet - at least Tja. Unfortunately, the CFP package is not listed. We could request a thermal model, but that can take up to 2-3 weeks.

    Hello Paul,

    Thanks for this quick answer! It's really appreciated ;-)

    This will permit me to coninue my thermal model.

    Regarding the Tja, the information is clearly listed in the DSCC specification (Section 1.3 Absolute Maximum Rating) for the CFP10 package (Case Outlines H). However, in my case, I needed to evaluate the theta_case_to_PCB, considering the vacuum conditions for my product. That's why I was looking for the base pin material

    Still thank you 

    Best Regards

    Bruno
