The heat sink size calculator first calculates the optimum spacing between the fins to achieve maximum convection cooling.
Power components have a maximum junction temperature which must not be exceeded to prevent damage to the device.
The width of the heat sink is then calculated based on the number of fins required to dissipate the heat from the heat sink.
