- Interface circuits for microcontrollers and logic devices
- Power supply feedback loops requiring galvanic isolation
Procurement Notes
Verify the specific suffix designation against official Everlight documentation to confirm pinout configuration and electrical characteristics. Ensure the selected variant matches the required package dimensions and thermal management needs for the target application environment.
Selection Notes
Select this component when high isolation voltage and compact form factor are required. Consider the 80V collector-emitter voltage limit and 50mA forward current constraints during circuit design. Verify compatibility with the system's operating temperature range and signal speed requirements given the specified rise and fall times.
Part Context
This part belongs to the EL3H4 series of transistor output optocouplers from Everlight. The series is designed for general-purpose isolation applications, offering reliable performance in a small footprint. Variants within the series may differ in internal LED configuration or package type, necessitating careful selection based on specific circuit requirements.
Replacement Considerations
Consult official Everlight documentation for confirmed substitute part numbers. Cross-referencing with other manufacturers requires verification of pinout, isolation voltage, and electrical parameters to ensure functional equivalence.
