Junction Temperature Calculation: T J = TA + (PD x θJA). Note B. The above numbers for θ JC are maximums for the limiting thermal resistance of the package in a standard mount- ing configuration. The θ JA numbers are meant to be guidelines for the thermal performance of the device/pc- board system. All of the above assume no ambient airflow. Note 2: Range over which the device is functional.
