I'm looking for the Thermal Resistance from junction to board  for the PowerSO20.  Do you have this information?

Hello @asubbiah 

The Thermal Resistance Junction-case and the Thermal Resistance Junction-ambient are indicated her:

You can find more in this datasheet.

Best regards.

Issamos,

The "-" out number is what I am looking for.  I'm trying to model this as a single resistor for my thermal model.  I am looking for the  junction to board resistance.  Do you know what this value would be? Do you have any guidance on how to model this component to predict junction temperatures?

Thanks,

AS
