PCB Thermal Calculator

The PCB Thermal Calculator is designed to estimate the junction temperatures of components which use exposed-pad packages.


PCB Thermal Calculator - this calculator uses the PCB copper area to estimate the device junction temperature. You must have JavaScript and Flash enabled to view this content.

More about the PCB Thermal Calculator:

  • The data used in the PCB Thermal Calculator is generated from measured laboratory data combined with thermal-modeling analysis that uses a series of thousands of data points.
  • The result of the correlation is used to create the curves and the data points that appear in the PCB Thermal Calculator.
  • The PCB Thermal Calculator also supports the input of the board temperature as a reference point. In this case, the junction temperature results are estimated independently of the PCB layout.
