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 76.2 x 114.3 x 1.5 mm³ board with 2 inner copper layers (2 x 70µm Cu, 2 x 35µm Cu).
Where applicable a thermal via array under the exposed pad contacted the first inner copper layer.
3) Specified RthJA value is according to JEDEC JESD 51-3 at natural convection on FR4 1s0p board; The Product
(Chip+Package) was simulated on a 76.2 à 114.3 à 1.5 mm3 board with 1 copper layer (1 x 70µm Cu).
