    Jayakumara,

    1) Tj max 150C
    2) Pd is set by application. Pd = [cathode voltage] * [cathode current]; For VKA=VREF and 10mA, Pd=2.495V*10mA = 25mW
    3) Maximum power dissipation is a function of TJ(max), TJA, and TA. The maximum allowable power dissipation at any allowable ambient
    temperature is PD = (TJ(max) – TA)/TJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
    4) Theta JA is 87C/W
    5) Theta JB is not specified in any data base
    6) Theta JC is 259C/W 
    7) Weight is 4.9g
