Our Mechanical team is doing a thermal study on the 65W project.
We are working on and they need Rjc(junction-to-top case) and Rjc (junction-to-bottom case) for CYPD3121-40LQXIT.
As these data are not indicated top or bottom case on your published datasheet of Tjc parameter.
Please help to check for this data.
Thanks,
Mitchell

Hi Mitchell,
Tjc in CCG3 datasheet represents for junction-to-top case thermal resistance. And we do not have data for junction-to-bottom thermal resistance. The device power consumption is a relatively a small number compared to Tjc number, which makes minor difference between top and bottom temperature.
Regards,
Eddie
