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 insula-
tion requirements. However, once mounted on a printed
circuit board, minimum creep-age 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
factors such as pollution degree and insulation level.

Method a/b partial discharge test profiles.
Note: These optocouplers are suitable for “safe electrical isolation” only within the safety limit data. Maintenance of the safety data shall be en-
sured by means of protective circuits. Surface mount classification is Class A in accordance with CECC 00802.
