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.

* θ can be improved with package soldered to 0.5IN2 copper area over backside ground

plane or internal power plane. θJAcan vary from 20ºC/W to > 40ºC/W depending on

mounting technique.
