Hi,

I can only find Ta, Tj and Rja in the datasheet.

Could you pleaes advise Ɵjc, power disspasition and surface case temperature?

Thank you so much!

Hi Tiger,

I am having the thermal modeling team generate the numbers now and I will follow up with you when I have the results.

Hi Tiger,

Sorry for the delay this slipped through the cracks on me. Here is the data for all the packages:

Hi Tiger,

I am not sure of the source of the old data so I cannot comment on how it was obtained. The new data was obtained using the latest JEDEC standards and modeling methodology and correlates with other devices using those packages.
