All Avago data sheets report the creepage and clearance

inherent to the optocoupler component itself. These

dimen­sions are needed as a starting point for the equip-

ment 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 stan-

dards. 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 insulation level.
