    Hello Mark,

    Thanks for the inquiry. Max thermal resistance, Rθjc(bottom) = 0.8°C/W, junction-to-case, and Rθja = 50°C/W, junction-to-ambient, is specified in Table 5.2 of the FET datasheets. The estimated thermal resistance thru the top of the package, Rθjc(top) is ~9°C/W for both devices. The CSD96497Q5MCT power stage is part of a different product line. I will reassign this thread to the power stage applications team. Please let me know if you need any additional information.

    Best Regards,

    Hi Mark,

    For the CSD96497Q5MCT, the typical thermal resistance, junction-to-case Rθjc (Top) = 5.8°C/W, junction-to-board Rθjb = 1°C/W, Ψjt = 0.2 °C/W.

    Best,

    Ryan
