I see on the data sheet that for device D the theta JA value is listed as 125 C/W what are the theta JB and theta JC values? Thanks

Hi Sean,

I went ahead and requested for the thermal values of this package. This usually takes about two weeks. I will get back to you as soon as I get the values.

Best Regards,

Ignacio

Hello Sean,

I apologize for the long delay here. We just received the thermal values for the OPA691ID. Below are the thermal values:

Result- Theta JA-High K (standard datasheet value)	126.5
Result-Theta JC, top (standard datasheet value)	67.1
Result-Theta JB (standard datasheet value)	73.6
Result- Psi JT (standard datasheet value)	14.0
Result- Psi JB (standard datasheet value)	72.7
Result-Theta JC, bottom (standard datasheet value)	n/a

We expect the OPA301 to be finished this week.

Thank you,

Sima
