* Isolation characteristics are guaranteed only within the safety maximum ratings which must be ensured by protective circuits in application.
Surface mount classification is class A in accordance with CECCOO802.
** Refer to the optocoupler section of the Isolation and Control Components Designer’s Catalog, under Product Safety Regulations section IEC/EN/
DIN EN 60747-5-2, for a detailed description of Method a and Method 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 ensured
by means of protective circuits.
Note: The surface mount classification is Class A in accordance with CECC 00802.

All Avago Technologies 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.
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.
