ROHS3 compliance means no substance-exemption tracking is needed for the BOM — the part ships lead-free and with the full RoHS exemption roll-up already handled. ## What the isolation and CTR ratings mean for the signal path The 2500Vrms isolation rating provides galvanic separation between the input LED side and the output Darlington transistor — this is the spec that protects low-voltage logic from ground loops, transient spikes, and common-mode voltage differences in industrial sensor interfaces, PLC digital inputs, and motor-drive feedback paths. Current transfer ratio spans 500% minimum to 2600% maximum at a forward current of 1.6mA. A 500% CTR means the output can sink 5× the LED drive current — at 1.6mA LED current, the output drives at least 8mA into the load. The wide CTR spread means the designer must budget for the minimum at the worst-case temperature and LED aging, not the typical value. Turn-on time is 300ns typical, turn-off is 1.6µs typical. The asymmetric switching limits the useful data rate to roughly 300-400 kbps in a digital isolator application — fine for 24V PLC input sampling, serial UART handshake, or slow PWM gate drive, but not for high-speed fieldbus isolation. ## Package and temperature range — board-fit and environment The Darlington output with a base pin brought out allows the designer to add a base resistor for switching speed adjustment or to tie the base to emitter for a standard photodarlington configuration.","metaTitle":"onsemi HCPL0701 Optocoupler, Darlington Output, 8-SOIC","metaDescription":"onsemi HCPL0701 single-channel optocoupler with Darlington output, 2500Vrms isolation, 500-2600% CTR.

This is sufficient for industrial control interfaces, PLC digital inputs, and motor-drive feedback where the working voltage is below 300V peak — but not for mains-referenced medical or 600V-class drive isolation, which typically requires 5000Vrms or higher."},{"question":"What compliance documentation does onsemi provide for the HCPL0701?","answer":"The HCPL0701 is ROHS3 compliant, covering all ten restricted substances without exemptions. onsemi provides a Certificate of Compliance and material declaration per the standard REACH and RoHS frameworks.
