Notes:
1. 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 pro les.
2. 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. Surface mount classi cation is Class A in accordance with CECC 00802.

Notes:
1. 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 speci ed for individual equipment standards. For creepage, the shortest
distance path along the surface of a printed circuit board between the solder llets 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.
