Notes

• Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not

implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute

maximum ratings for extended periods of the time can adversely affect reliability

(1) Refer to wave profile for soldering conditions for through hole devices (DIP)

Notes

• 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

(1) For 2 layer FR4 board (4" x 3" x 0.062")
