Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify component authenticity through authorized distributors as the part is listed as obsolete. Confirm RoHS compliance status via official datasheets before integration. Check for valid substitute part numbers such as CNY172VM if sourcing new production units is not feasible. Ensure storage conditions meet manufacturer specifications to maintain reliability.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when base-controlled phototransistors are required for faster switching applications compared to standard variants. The SMD-DIP-6 form factor suits designs needing DIP pin compatibility with surface-mount processing. Verify that the 30 V collector-emitter voltage and 100 mA current ratings align with load requirements. Consider the extended operating temperature range for harsh environments.

Transistor, Photovoltaic Output Optoisolators Part Context

The CNX35U300 belongs to onsemi's family of transistor output optoisolators. It is designed to provide reliable signal transfer while maintaining electrical separation. The inclusion of a base terminal distinguishes it from basic phototransistor optocouplers, offering better control over saturation and turn-off times. This series is commonly used in general-purpose isolation tasks where moderate speed and high voltage isolation are necessary.
