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 and

package) was simulated on a 76.2 × 114.3 × 1.5 mm3 board with two inner copper layers (2 × 70 µm Cu, 2 × 35 µm Cu). Where

applicable, a thermal via array next to the package contacted the first inner copper layer.

3)

Package mounted on PCB FR4; 80 × 80 × 1.5 mm3; 35 µm Cu, 5 µm Sn; horizontal position; zero airflow.
