Hello Chino-san,

I requested a new thermal model, this process takes 2 days to 2 weeks. Average is 1 week.

Chino-san,

The model results are ready. The data is based on simulated thermal models using the build materials of the device. This data is not part of the data sheet and is only for informational purposes.

Theta JA-High K : 88.5 C/W
Theta JC, top : 41.6 C/W
Theta JB : 76.0 C/W
Psi JT : 35.0 C/W
Psi JB : 71.1 C/W
Theta JC, bottom : 22.6 C/W
