Procurement Notes

Verify the specific suffix X017T against official Vishay documentation to confirm reel quantity and tape specifications. Confirm RoHS compliance status as indicated in manufacturer datasheets. Ensure the absence of zero-crossing circuitry aligns with application requirements before procurement.

Selection Notes

Select this component when high isolation voltage and robust AC switching capability are required in a compact surface-mount form factor. Consider the lack of zero-crossing detection if noise immunity or EMI reduction during switching is critical for the specific design.

Part Context

This part belongs to Vishay's triac and SCR output optocoupler family. It is designed for applications requiring galvanic isolation between low-voltage control circuits and higher-voltage AC loads. The SMD variant facilitates automated assembly in modern electronic manufacturing processes.

Replacement Considerations

Consult official Vishay substitution guides for direct replacements. Verify pinout compatibility and electrical parameter equivalence for any alternative components.
