Overview
The EL354(A)-V is a single-channel optocoupler featuring an infrared LED input and a phototransistor output, housed in a compact SOP-4 surface-mount package. It provides electrical isolation between input and output circuits with a rated isolation voltage of 3750Vrms. The device supports both AC and DC input signals and offers a typical forward voltage of 1.2V. It operates within a temperature range of -55°C to 100°C and includes a maximum DC forward current rating of 50 mA.
Feature Summary
- Provides high-voltage electrical isolation for signal transmission between separate circuits
- Integrates an infrared emitter and phototransistor for efficient electro-optical conversion
- Compatible with both alternating and direct current input signal types
Applications
- Digital logic signal transmission and level shifting

- Electrical insulation between system components
- Impedance transformation in electronic interfaces
Procurement Notes
Verify the specific suffix designation against official Everlight documentation to confirm pin configuration and packaging variations. Ensure the selected variant matches the required isolation voltage and operating temperature specifications for the target application environment.
Selection Notes
Select this component when compact surface-mount isolation is required for low-power digital or analog signal coupling. Consider the 3750Vrms isolation rating for safety-critical applications and verify compatibility with the driving circuit's current limitations and load requirements.
Part Context
This part belongs to the EL354 series of transistor-output optocouplers manufactured by Everlight Electronics. The series is designed for general-purpose isolation tasks, offering a balance of performance and size through its SOP-4 footprint, suitable for dense PCB layouts in consumer and industrial electronics.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Generic replacements may differ in isolation voltage or CTR specifications; ensure any alternative meets the original design's safety and electrical constraints.
