TMUXHS4212: Junction temp

Hi Adam,

You can estimate the maximum junction temperature based on following equation. Assume the top case temperate is equal to Ta. 

The max junction temperature calculated above is how hot the IC can get if the device is operated a) within the recommended operating conditions and b) in such a way to try and create the most heat inside the device. Since signal switches are low power devices they will not get very hot even if you are operating the device to its maximum limits stated in the datasheet.

Please refer to the app note below for more information on thermal parameters and refer to the equation above in section 3 ΨJT, Junction to Top of Package. 

Thanks Malik,

Are you able to provide the app note you referenced? It looks like you forgot to include it...

Best,

Adam
