2) Specified R_thJA value is according to Jedec JESD51-2,-5,-7 at natural convection on FR4 2s2p board; the Product
(Chip+Package) was simulated on a 76.2 * 114.3 * 1.5 mm board with 2 inner copper layers (2 * 70 µm Cu, 2 * 35 µm Cu).
Where applicable a thermal via array under the exposed pad contacted the first inner copper layer.
