I'll submit a request for a new thermal model simulation that includes all parameters. I would expect results in about 1 week.

Thanks
Christian

Hi again,

Just to update you on this request, I just checked and the thermal model is not yet available. Once I receive the information, I will forward to you.

Thanks
Christian

Hi,

Here is the complete thermal model for the OPA4872-EP.

Theta JA-High K = 86.1 C/W
Theta JC, top = 43.1 C/W
Theta JB = 42.2 C/W
Psi JT = 9.8 C/W
Psi JB = 41.9 C/W
Theta JC, bottom = n/a

If this answered your question please click on the appropriate box.

Thanks
Christian
