(1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application
report (SPRA953).
(2) No heat sink is assumed for these estimations. Depending on the application, a heat sink, faster air flow, and/or reduced ambient
temperature (<85°C) may be required in order to maintain the maximum junction temperature specified in Electrical Characteristics.
