Note 1. Maximum power dissipation is a function of TJ(max), JA, and TA. The maximum allowable power dissipation
at any allowable ambient temperature is P
= (TJ(max) TA)/JA. 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.
