NOTE
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 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 (the
recommended Land Pattern does not necessarily meet the minimum creepage of the device). There are
recommended techniques, such as grooves and ribs, that 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.
