Note
The thermal model is represented in the thermal network below.
Each resistance value given in this model can be used to calculate
the temperatures at each node for a given operating condition. The
thermal resistance from board to ambient will be dependent on the
type of PCB, layout and thickness of copper traces. For a detailed
explanation of the thermal model, please reference Vishay's
Thermal Characteristics of Power Phototriac application note.
