1) Not subject to production test. Specified by design.
2)Specified Rthja value is according to JEDEC JESD51-2,-5,-7 at natural convection on FR4 2s2p board; The
product (chip + package) was simulated on a 76.4 x 114.3 x 1.5 mm board with 2 inner copper layers (2 x 70μm
Cu, 2 x 35 μm Cu). Where applicable, a thermal via array under the exposed pad contacts the first inner copper
layer. Please refer to Figure 4 and Figure 5.
