Note 1. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation
at any allowable ambient temperature is PD = (TJ(max) − TA)/θJA. Operating at the absolute maximum TJ of
150°C can affect reliability.
2. The package thermal impedance is calculated in accordance with JESD 51-7.
