INA159: Thermal Resistance Junction to Case

Errol Leon6

Part Number: INA159


Hello team,

My customer is considering using the INA159AIDGKR and wanted to know what the thermal resistance junction-to-case.  It looks like in the datasheet we specify junction-to-ambient but it doesn't state junction-to-case.  Do we have any information on junction-to-case thermal resistance?

Thank you in advance for your support!

    Hi Errol,

    Thanks for your post, I can help you. Typically, only power packages specify junction-to-case thermal resistance. Since the INA159 is offered in a standard MSOP-8 package, there is no need for the junction-to-case spec. The junction-to-ambient is available in the datasheet as you pointed out, though.
