). The
θ
numbers are guidelines for the
thermal performance of the device/pc-board system. All of the above assume no ambient airflow.

copper area over backside ground
plane or internal power plane.
θ
can vary from 20oC/W to > 40oC/W depending on
mounting technique. (See Application Notes Section: Thermal Considerations)
