5 / 18 page 5 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 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 Insulation and Safety Related Specifications Value Parameter Symbol 772X 072X Units Conditions Minimum External Air L(I01) 7.1 4.9 mm Measured from input terminals to output Gap (Clearance) terminals, shortest distance through air. Minimum External L(I02) 7.4 4.8 mm Measured from input terminals to output Tracking (Creepage) terminals, shortest distance path along body. Minimum Internal Plastic 0.08 0.08 mm Insulation thickness between emitter and Gap (Internal Clearance) detector; also known as distance through insulation. Tracking Resistance CTI ≥175 ≥175 Volts DIN IEC 112/VDE 0303 Part 1 (Comparative Tracking Index) Isolation Group IIIa IIIa Material Group (DIN VDE 0110, 1/89, Table 1) 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.
