Its 5000Vrms isolation rating makes it a fit for safety-barrier applications in motor drives, industrial power supplies, and PLC I/O modules where galvanic separation between control and power domains is required. The base terminal allows the designer to tailor switching thresholds or add feedback compensation, a feature not available on standard three-pin optocouplers. The 50% minimum current transfer ratio at 10mA forward current is the spec that determines whether the output can drive a logic input or a small load across the isolation barrier — a CTR below 50% at the operating If means the output may not saturate cleanly, especially at cold temperature. The Vce saturation of 300mV max at rated current keeps the output drop low enough for 5V logic families without an extra pull-up resistor. Output rated to 32V and 50mA per channel gives headroom for driving 24V industrial logic inputs or small relays directly. Rise and fall times of 7µs and 6.7µs typical are adequate for 10 kHz to low-100 kHz switching; for faster signals, a logic-output optocoupler would be needed. The 1.25V typical forward voltage and 60mA max forward current are standard for an IR LED input stage, compatible with 3.3V and 5V logic outputs through a series resistor.","metaTitle":"CQY80N Optoisolator, 5000Vrms, Transistor Output, 6-DIP","metaDescription":"CQY80N optoisolator with 5000Vrms isolation, 50% min CTR, 32V/50mA output, -55°C to 100°C.

This is the guaranteed transfer ratio at the test condition — actual CTR will be higher across most of the operating range, but the 50% floor is the number to use for worst-case logic-level design."},{"question":"Can I use CQY80N in 5V logic circuits?","answer":"Yes. The 300mV max Vce saturation and 50% minimum CTR at 10mA If mean the output can pull a 5V logic input low reliably through a pull-up resistor. The 32V output max also allows direct interface to 24V industrial logic levels with appropriate collector load."},{"question":"What is the difference between CQY80N and CQY80?","answer":"The difference is package form factor and mounting. CQY80N is supplied in Tube packaging and uses a through-hole 6-DIP (0.300\", 7.62mm) package. The CQY80 variant typically differs in packaging or lead form — verify the specific suffix against your assembly process. Both share the same 5000Vrms isolation and transistor-with-base output."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay/CQY80N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay/CQY80N when reusing this data.
