The use of this device in one- or two-layer board designs is not recommended due to the limited thermal conductance
provided by those boards.

recommends the use of 
temperatures from exceeding the rated specification. System designers should be aware that device junction temperatures
can be significantly influenced by board layout and surrounding devices. Conformance to the device junction temperature
specification can be verified by physical measurement in the customer’s system using the 
dissipation, and the method described in EIA/JESD Standard 51-2.
Per JEDEC JESD51-6 with the board horizontal.
Thermal resistance between the die and the printed circuit board in conformance with JEDEC JESD51-8. Board
temperature is measured on the top surface of the board near the package.
Thermal resistance between the die and the case top surface as measured by the cold plate method (MIL SPEC-883
Method 1012.1).
