8 / 16 page Broadcom - 8 - ACPL-M21L, ACPL-021L, ACPL-024L, ACPL-W21L, ACPL-K24L Data Sheet NOTE These optocouplers are suitable for "safe electrical isolation" only within the safety limit data. Maintenance of the safety limit data shall be ensured by means of protective circuits. Table 3 Insulation and Safety Related Specifications Parameter Symbol ACPL-M21L ACPL-024L ACPL-021L ACPL-W21 ACPL-K24L Units Conditions Minimum External Air Gap (Clearance) L(101) 5 4.9 8 mm Measured from input terminals to output terminals, shortest distance through air. Minimum External Tracking (Creepage) L(102) 5 4.8 8 mm Measured from input terminals to output terminals, shortest distance path along body. Minimum Internal Plastic Gap (Internal Clearance) 0.08 0.08 0.08 mm Through insulation distance conductor to conductor, usually the straight line distance thickness between the emitter and detector.
