- Utilizes an NPN phototransistor for digital signal switching applications
- Operates reliably across extended industrial temperature ranges
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission in noisy electrical environments
- Microcontroller interface circuits with voltage level shifting
Procurement Notes
Verify the specific suffix (D)(TA)-G against official Everlight documentation to confirm pinout compatibility and packaging type. Ensure the component meets required isolation standards for the target application. Cross-reference datasheet parameters such as current transfer ratio and saturation voltage before integration into final designs.
Selection Notes
Select this component when a small form factor is required alongside high isolation voltage capabilities. The SSOP-4 package suits space-constrained printed circuit board layouts. Consider the operating temperature range and output type suitability for the specific logic family being interfaced.
Part Context
This part belongs to the EL3H7 series of transistor output optocouplers from Everlight. The series is characterized by its compact footprint and robust isolation performance. Variations within the series typically differ by packaging style or specific electrical parameter tolerances defined by the manufacturer.
Replacement Considerations
Consult official substitution guides for compatible equivalents. Verify that any alternative component matches the SSOP-4 package dimensions and pin configuration to ensure mechanical compatibility without redesigning the footprint.
