Note 1: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable
junction temperature and the thermal resistance from junction to air (i.e., TA, TJ, ï±JA). Exceeding the
maximum allowable power dissipation will cause the device operating junction temperature to exceed the
maximum +125°C rating. Sustained junction temperatures above +125°C can impact the device reliability.
2: PD(MAX) = (TJ(MAX) â TA)/ï±JA, where ï±JA depends upon the printed circuit layout. A 5 square inch 4 layer,
0.62â, FR-4 PCB with 2 oz. finish copper weight per layer is used for the ï±JA.
