Insulation and Safety Related Specifications
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 equip-
ment designer when determining the circuit insulation
requirements. However, once mounted on a printed
circuit board, minimum creepage and clearance require-
ments 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 fac-
tors such as pollution degree and insulation level.
