The thermal resistance for a particular application can and will vary widely depending on the external factors that affect the thermal resistance from junction to ambient.

There are a number of methods to measure the die temperature, such as infrared and liquid crystal sensing, but the most commonly used is the voltage drop across a forward-biased diode. The following table provides θ JA (junction-to-ambient thermal resistance) and θ JC (junction-to-case thermal resistance) values for the devices. The QFN package exposed pad (or paddle) offers a low thermal resistance path for heat transfer to the PCB and therefore it’s recommended to solder the exposed pad to a large conductive surface such as GND plane.
