    Hirano-san,

    I can put in a request for the thermal characteristics for the TCA6418E, but if these can be accomplished, they usually take multiple weeks to receive. I will follow up here within three weeks with the results I receive.

    Best,

    Danny

    Hirano-san,

    Thank you for your patience with this. The results for your inquiry are below.

    Thermal Analysis for TCA6418EYFPR

    Parameter Value Unit
    RθJA - High K Junction-to-ambient thermal resistance 64.4 °C/W
    RθJC(top) Junction-to-case (top) thermal resistance 0.4 °C/W
    RθJB Junction-to-board thermal resistance 14.1 °C/W
    ΨJT Junction-to-top characterization parameter 0.2 °C/W
    ΨJB Junction-to-board characterization parameter 14.0 °C/W
    RθJC(bot) Junction-to-case (bottom) thermal resistance N/A °C/W

    Per the datasheet, the operating free-air temperature of the TCA6418E is -40°C to +85°C, while the storage temperature range of the device is -65°C to +150°C.

    Best,
