Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the manufacturer designation carefully, as historical records indicate Fairchild Semiconductor production before acquisition by onsemi. Confirm the specific ordering suffix matches the required packaging format, such as tube or tape-and-reel variants if available. Ensure the component meets RoHS compliance requirements for the intended market. Cross-reference the datasheet revision date to confirm parameter consistency against current design specifications.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is necessary within a compact surface-mount footprint. The 8-SOIC package offers a balance between pin count and board space efficiency. Consider the 30 V collector-emitter voltage limit for low-voltage logic interfacing applications. The 20% minimum CTR ensures adequate signal transmission for standard digital switching speeds without requiring excessive drive current.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the MOCD series of transistor output optocouplers designed for general-purpose isolation tasks. It serves as a bridge between low-voltage control circuits and higher-power loads while maintaining electrical safety barriers. The dual-channel design allows for cost-effective implementation of multi-signal isolation compared to using single-channel devices.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes may include other dual-channel transistor optocouplers with similar 2500 Vrms isolation and SO-8 packaging. Verify that replacement parts match the 30 V Vceo and 150 mA Ico limits. Check compatibility with existing PCB footprints and thermal dissipation requirements.
