THERMAL CHARACTERISTICS
PARAMETER
Maximum LED junction temperature
Maximum output die junction temperature
Thermal resistance, junction emitter to board
Thermal resistance, junction emitter to case
Thermal resistance, junction detector to board
Thermal resistance, junction detector to case

Thermal resistance, case to ambient
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.
For 2 layer FR4 board (4" x 3" x 0.062).
