• Includes a dedicated base terminal on the phototransistor to allow for faster switching speeds and improved noise immunity.
• Designed for robust signal transmission across high-voltage barriers with specified insulation voltage ratings.

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring isolated signal interfacing
• Microcontroller input/output isolation for noise reduction
• Power supply feedback loops for voltage regulation

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify component authenticity due to obsolete status. Confirm package integrity as storage duration may affect lead frame oxidation. Ensure compatibility with existing PCB footprints since DIP-6 dimensions are standardized but verify pin alignment. Check RoHS compliance documentation if required for specific regulatory environments. Source only from authorized distributors to avoid counterfeit risks associated with end-of-life parts.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage and fast switching are required in a through-hole configuration. The presence of a base terminal distinguishes it from standard phototransistors, offering better performance in noisy environments. Consider thermal management as power dissipation reaches 250 mW. Evaluate alternative surface-mount versions if space constraints exist, though package changes require schematic updates.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the CNY172 family of transistor output optocouplers. It represents a legacy product line from onsemi (formerly Fairchild Semiconductor). The FR2 suffix typically indicates specific tape and reel packaging or regional variants within the broader CNY172 series. It serves as a general-purpose isolator for digital signal transmission.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

H11N1SR2VM is listed as a similar replacement option by distributors, though it differs in package type and speed characteristics. Verify functional equivalence before substitution.
