Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix designation to confirm the current transfer ratio bin, as variants exist within the CNY117 series. Ensure the procurement order matches the required packaging format, such as tube or reel, based on assembly needs. Confirm RoHS compliance status and check for any recent manufacturing updates that may affect lead times or component specifications before finalizing orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a standard NPN phototransistor output with moderate speed is required. The DIP-6 package suits through-hole designs. Consider higher CTR variants if greater sensitivity is needed, or SMD versions like the CNY117F series for surface mount applications. Verify that the 50 mA collector current limit meets the load requirements of the target circuit.

Transistor, Photovoltaic Output Optoisolators Part Context

The CNY117-1 belongs to the CNY family of optocouplers, designed for general-purpose isolation tasks. It shares the same physical footprint and basic electrical characteristics with other CNY117 variants, differing primarily in the current transfer ratio classification. This specific model represents the lower end of the CTR spectrum within the DIP-6 through-hole lineup.
