The values in Table 7 are per JEDEC JESD51-7 plus JEDEC
JESD25-5 for a 2S2P test board. Typical θJA is specified for a
4-layer PCB with a solid ground plane. As shown in Table 7,
airflow improves heat dissipation, which reduces θJA. In addi-
tion, metal in direct contact with the package leads from metal
traces, through holes, ground, and power planes reduces θJA.

3 Per JEDEC JESD51-8 (still air).
The values in Table 8 are from simulations. The PCB is a JEDEC
multilayer board. Thermal performance for actual applications
requires careful inspection of the conditions in the application
to determine whether they are similar to those assumed in these
calculations.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
