Procurement Notes

Verify the specific suffix X006 corresponds to the tube packaging format when sourcing components. Confirm that the requested part matches the Vishay Semiconductor Opto Division manufacturer designation to ensure authenticity. Cross-reference the datasheet revision date against project requirements to guarantee parameter consistency. Ensure compliance with RoHS directives if applicable to the target assembly standards before finalizing procurement orders.

Selection Notes

Select this component when a through-hole DIP-4 package is required for manual assembly or rework flexibility. Choose the SFH617A-1X006 over surface mount variants if board space allows for larger footprints but higher mechanical stability is needed. Consider the 40-80% current transfer ratio range when designing biasing networks to ensure consistent switching performance across all production units without excessive margin requirements.
