Overview
The onsemi CNY17F3 is a single-channel optocoupler featuring an NPN phototransistor output and a gallium arsenide infrared LED input. It provides electrical isolation with a maximum forward voltage of 1.65V and a collector-emitter voltage rating of 70V. The device supports a maximum DC forward current of 60mA and offers a typical rise time of 6µs alongside a fall time of 24µs. It utilizes a 6-pin MDIP package and delivers an isolation voltage of 7500 Vrms, ensuring reliable signal transmission between circuits.
Feature Summary
- Provides galvanic isolation between input and output circuits using an infrared LED and phototransistor pair.
- Features a standard 6-pin MDIP package suitable for through-hole mounting applications.
- Delivers high isolation voltage capability to protect sensitive control circuitry from high-voltage transients.
Applications
- Signal isolation in industrial automation control systems
- Input/output interface isolation in microcontroller-based designs
- Power supply feedback loop isolation
Procurement Notes
Verify the specific suffix (e.g., F3SM, SR2VM) against project requirements, as packaging and minor electrical tolerances vary by variant. Confirm RoHS compliance status via the manufacturer's latest material declaration. Ensure the selected package type matches the PCB footprint design before finalizing procurement orders.
Selection Notes
Select this component when a standard transistor-output optocoupler is required for general-purpose isolation. Consider the 60mA forward current limit and 70V collector-emitter voltage for circuit compatibility. Evaluate the 6µs rise time against system speed requirements to ensure adequate signal integrity for the intended application frequency.
Part Context
The CNY17F3 belongs to the widely used CNY17 family of optocouplers manufactured by onsemi. This series is established for providing cost-effective isolation solutions in various electronic designs. The specific model variants differ primarily in packaging formats and reel specifications while maintaining core electrical characteristics.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical ratings before considering alternative manufacturers or generic equivalents.
