Isolation Group
All Agilent 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

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.
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.
