8 / 19 page 8 All Avago data sheets report the creepage and clearance inherent to the optocoupler component itself. These di- mensions 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, mini- mum creepage and clearance requirements must be met as specified for individual equipment standards. For Insulation and Safety Related Specifications Parameter Symbol Value Units Conditions HCPL- 4504 HCPL- J454 -400E/-600E HCPL-J454 All other options HCPL- 0454 HCNW 4504 Minimum External Air Gap (External Clearance) L(101) 7.1 8.0 7.4 4.9 9.6 mm Measured from input ter- minals to output terminals, shortest distance through air. Minimum External Tracking (External Creepage) L(102) 7.4 8.0 8.0 4.8 10.0 mm Measured from input ter- minals to output terminals, shortest distance path along body. Minimum Internal Plastic Gap (Internal Clearance) 0.08 0.5 0.5 0.08 1.0 mm Through insulation distance, conductor to conductor, usually the direct distance between the photoemitter and photodetector inside the optocoupler cavity. Minimum Internal Tracking (Internal Creepage) NA NA NA NA 4.0 mm Measured from input ter- minals to output terminals, along internal cavity. Tracking Resistance (Comparative Tracking Index) CTI ≥175 ≥175 ≥175 ≥175 ≥200 Volts DIN IEC 112/VDE 0303 Part 1 Isolation Group IIIa IIIa IIIa IIIa IIIa Material Group (DIN VDE 0110, 1/89, Table 1) 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 clear- ance distances will also change depending on factors such as pollution degree and insulation level.
