• Industrial drive applications
• Energy infrastructure systems

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify component obsolescence status before integration, as the CNW83300 is officially discontinued. Confirm RoHS compliance requirements, noting this specific part does not meet current standards. Validate physical dimensions against the 6-DIP (0.400 inch) footprint. Ensure supply chain sources provide authentic documentation to avoid counterfeit risks associated with end-of-life components.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component only if legacy system compatibility requires the specific wide-body DIP form factor and 5900Vrms isolation rating. Evaluate the trade-off between the connected base pin configuration and noise immunity needs compared to non-base variants. Consider the discontinuation status when planning long-term production lifecycles and potential redesign efforts.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the CNW82-85 family of wide-body, high-isolation optocouplers from onsemi. These units utilize a GaAs infrared LED coupled to an NPN phototransistor. Unlike the CNW82 and CNW84 models which leave the base unconnected for superior noise immunity, the CNW83 series includes a base pin connection to optimize performance characteristics for specific circuit driving requirements.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The CNY171M is identified as a similar replacement option available from onsemi. Verify functional equivalence regarding pinout, isolation ratings, and electrical characteristics before substitution in existing designs.

Transistor, Photovoltaic Output Optoisolators FAQ

What is the difference between the CNW83300 and the CNW82/84 models?

The CNW83300 features a connected base pin on the NPN phototransistor, whereas the CNW82 and CNW84 models do not have the base pin connected, which is designed to improve noise immunity.

What is the minimum creepage distance for this component?

The wide body DIL encapsulation provides a minimum creepage distance of 10 mm.
