Junction Temperature Calculation: TJ = TA + (PD x θJA).
The θJA numbers are guidelines for the thermal performance of the device/pc-board
system. All of the above assume no ambient airflow. θJA can vary from 20°C/W to >
40°C/W depending on mounting technique. (See Application Notes Section: Thermal
considerations)
