- Solid-state relay driver circuits
Procurement Notes
Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct packaging and compliance status. Confirm that the component meets required safety certifications such as UL or VDE if used in regulated equipment. Check for end-of-life status or alternative sourcing options through authorized distributors.
Selection Notes
Select this component when high isolation voltage and compact SMD footprint are required. Ensure the application current requirements fall within the specified forward and collector current limits. Consider the thermal management needs given the wide operating temperature range and surface-mount construction.
Part Context
This part belongs to the EL816 series of transistor output optocouplers from Everlight. The series is designed for general-purpose isolation applications. The specific model indicates a surface-mount variant with defined pin configuration and isolation characteristics consistent with the broader family specifications.
Replacement Considerations
Compatible substitutes include other 4-pin SMD transistor optocouplers with similar isolation ratings and pinouts. Verify pin compatibility and electrical parameters before substitution.
