Thermal Management Information

This table shows heat sinks and junction-to-ambient thermal resistance for TBGA package.

Accurate thermal design requires thermal modeling of the application environment using computational fluid dynamics

software which can model both the conduction cooling and the convection cooling of the air moving through the application.

Simplified thermal models of the packages can be assembled using the junction-to-case and junction-to-board thermal

resistances listed in the thermal resistance table. More detailed thermal models can be made available on request.
