(1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application note.
(2) The maximum power dissipation is a function of TJ(MAX), RθJA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX) – TA) / RθJA. All numbers apply for packages soldered directly onto a PCB.
