CNY17-3M-V

Transistor, Photovoltaic Output Optoisolators Overview

The CNY17-3M-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output with a base connection, housed in a surface-mount 6-DIP package. The device provides high isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a collector-emitter breakdown voltage of 80 V, a maximum forward current of 60 mA, and a forward voltage of 1.65 V. The current transfer ratio ranges from 100% to 200%. Operating temperatures span from -55°C to +110°C, with power dissipation rated at 200 mW.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'V' indicates the RoHS-compliant version and surface-mount configuration distinct from through-hole variants. Confirm the manufacturer part number matches Everlight's official documentation to ensure correct pinout and electrical characteristics. Check for UL and VDE approval status if regulatory compliance is required for the end application.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a surface-mount solution is preferred over traditional through-hole packages while maintaining high isolation requirements. The inclusion of a base connection allows for improved switching speed or noise reduction compared to base-less variants. Ensure the 100-200% current transfer ratio meets the drive requirements of the downstream logic or transistor stage.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the CNY17 series of transistor output optocouplers. Unlike the standard CNY17-3 which uses a through-hole DIP-6 package, the CNY17-3M-V utilizes a surface-mount variant. It shares similar electrical performance characteristics with other members of the family but differs in physical mounting style and potentially in specific manufacturing lot markings.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes within the same family include CNY17-3S(TA)-V for surface-mount applications with identical electrical specs. For through-hole replacements, the CNY17-3 may be considered if board layout permits. Verify pin compatibility and thermal management requirements when swapping between SMD and THT versions.
