Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., DG) against the manufacturer's official datasheet to confirm pinout compatibility and packaging variations. Ensure the selected variant meets the required isolation voltage and current transfer ratio specifications for the target application environment.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a base-controlled phototransistor output is required for precise switching characteristics. Compare the 40-80% current transfer ratio against system requirements. Confirm that the 6-pin DIP form factor fits the available PCB space and mounting constraints.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the Isocom Components 2004 LTD portfolio of optocouplers. It shares the standard 6-pin DIP footprint common to many industry-standard isolators but distinguishes itself through the inclusion of a base terminal on the output transistor for improved performance flexibility.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Cross-reference with CNY17-1 variants or similar 6-pin DIP optocouplers featuring base outputs. Verify that substitute parts match the 5300Vrms isolation rating and comparable current transfer ratios before implementation.
