plane area relationship, the maximum allowable power dissipation could be evaluated with respect to the  
ambient temperature. As shown in graph, the higher copper plane area leads θJA. And the higher ambient  
temperature leads lower maximum allowable power dissipation.  
All this relationship is based on the aforesaid equation ; θJA = TRmax / PD = (TJmax – TAmax) / PD  
The graph below is valid for the thermal resistance specified in the Thermal Information section on page 2.
