(1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application report.

(2) The package thermal resistance is calculated on a 4 layer JEDEC board.

(3) Connected to GND with 3 thermal vias (0.3-mm diameter).

(4) ψJB (junction to board) is used when the main heat flow is from the junction to the GND pad. Please refer to Thermal Considerations section for more information on ensuring good system reliability and quality.
