All Avago data sheets report the creepage and clearance inherent to the optocoupler component itself. These dimen-
sions are needed as a starting point for the equipment designer when determining the circuit insulation requirements.
However, once mounted on a printed circuit board, minimum creepage and clearance requirements must be met as
specified for individual equipment standards. For creepage, the shortest distance path along the surface of a printed
circuit board between the solder fillets of the input and output leads must be considered. There are recommended
techniques such as grooves and ribs which may be used on a printed circuit board to achieve desired creepage and
clearances. Creepage and clearance distances will also change depending on factors such as pollution degree and in-
sulation level.
