    [FAQ] How to calculate max junction temperature (Tj max) and max power dissipation for an analog switch

    • Answered
    Please can anyone point me in the direction of the Tj max for the TS5A21366 Analogue Switch? This data is not in the datasheet, and is needed for derating the part in my application. The only information is the max ambient temperature, and the theta JA, so I can loosely approximate what the junction...
