Procurement Notes
Verify the specific suffix 'SM' confirms the surface mount variant against official datasheets. Ensure compatibility with automated placement equipment. Confirm lead form specifications match design requirements. Check for any custom electrical selection options if standard parameters are insufficient. Validate UL recognition status for end-product compliance.
Selection Notes
Select this component for applications requiring high density mounting and galvanic isolation. Consider the photodarlington output for high gain needs. Evaluate thermal management within the DIP package constraints. Compare isolation voltage ratings against system safety standards. Assess current transfer ratio requirements for logic level interfacing.
Part Context
This part belongs to the ISP series of high-density mounting phototransistor and photodarlington optically coupled isolators. The series offers various lead forms including standard through-hole and surface mount options. These components are designed for reliable signal transmission in compact electronic designs.
Replacement Considerations
Consult official substitution lists for equivalent photodarlington optocouplers. Verify pinout compatibility before replacement. Ensure isolation voltage and current transfer ratio meet or exceed original specifications.
