(1) The junction to ambient thermal resistance (RθJA ) under natural convection is obtained in a simulation on a JEDEC-standard, High-K board as specified in JESD51-7, in an environment described in JESD51-2. Exposed pad packages assume that thermal vias are included in the PCB, per JESD 51-5.
(2) Changes in output due to self heating can be computed by multiplying the internal dissipation by the thermal resistance.
