PCB thermal calculator
The PCB thermal calculator helps you estimate the junction temperatures of components which use exposed-pad packages. This tool generates a quick estimate of the expected junction temperature based on the copper spreading area on the PCB.
Temperature vs. PCB copper coverage area
Minimum Thermal = single thermal spreading plane of 1/2 oz Cu
