    Hi Suzanne,

    Based on a couple of TI thermal databases and the thermal tables for other products, the SO-8 SOIC (D) package would have a θJC in the 40°C/W to 50°C/W range. The INA137's θJA figure is shown below. 

     

    If you have additional questions, please let us know. 

    Best,

    Raymond
