Notes
(1)
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 Optocouplers Application note.
(2)
For 2 layer FR4 board (4" x 3" x 0.062).
