Overview
The EL354(TA) is a single-channel optoisolator manufactured by Everlight Electronics Co Ltd. It features a phototransistor output and utilizes a 4-SOP surface-mount package with gull-wing leads. The device provides an isolation voltage of 3750Vrms, ensuring robust separation between input and output circuits. Typical electrical characteristics include a forward voltage of 1.2V and a maximum output voltage of 80V. Rise and fall times are specified at 6µs and 8µs respectively, supporting standard digital signal isolation requirements.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Integrates a phototransistor for reliable signal transmission
- Designed for surface-mount assembly in compact electronic systems
Applications
- Digital signal isolation in communication interfaces
- Protection of sensitive control circuits from high-voltage transients
- Microcontroller interface isolation in industrial automation
Procurement Notes
Verify the specific suffix designation against official Everlight documentation to confirm pinout and performance specifications. Ensure the procurement source provides valid manufacturer traceability. Confirm compliance with relevant environmental standards prior to integration into final assemblies.
Selection Notes
Select this component when a single-channel transistor-output isolator is required for moderate-speed applications. Evaluate the 3750Vrms isolation rating against system safety requirements. Consider the 4-SOP package dimensions for PCB layout constraints and thermal management needs during design.
Part Context
This component belongs to the Everlight optoisolation product family, designed for general-purpose signal transfer across isolated boundaries. The EL354 series offers a balance of isolation performance and cost-effectiveness for consumer and industrial electronics requiring galvanic separation.
Replacement Considerations
Consult official Everlight documentation for verified substitute part numbers. Cross-referencing requires matching isolation voltage, output type, and package dimensions.
