Overview
The EL354(A)(TA)-V is a single-channel phototransistor output optoisolator manufactured by Everlight Electronics. It integrates an infrared emitting diode with a phototransistor in a 4-pin SOP surface-mount package. The device provides electrical isolation with a rated voltage of 3750Vrms. Key electrical parameters include a minimum current transfer ratio of 50% and a maximum of 150% at a forward current of 1mA. The output can withstand a maximum voltage of 80V, while the input forward voltage is typically 1.2V. The component supports a maximum DC forward current of 50mA and operates within a temperature range of -55°C to 100°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Integrates infrared LED and phototransistor for efficient signal transmission
- Designed for surface-mount assembly in compact electronic systems
Applications
- Digital logic signal transmission and level shifting
- Power supply control and switching circuits

- Impedance transformation between system components
Procurement Notes
Verify the specific suffix configuration against official Everlight documentation to ensure correct pinout and performance characteristics. Confirm RoHS compliance status and packaging details directly from the manufacturer's datasheet or authorized distributor catalogs before finalizing procurement orders.
Selection Notes
Select this component when high isolation voltage is required in a small surface-mount footprint. Ensure the application voltage does not exceed the 80V output rating. Verify that the required current transfer ratio falls within the specified 50% to 150% range for the intended operating conditions.
Part Context
This part belongs to the EL354 series of phototransistor output optocouplers. It is designed for general-purpose isolation applications where space constraints necessitate a surface-mount package. The series offers reliable performance for digital and analog signal isolation in industrial and consumer electronics.
Replacement Considerations
Consult official substitution guides for compatible alternatives. Cross-referencing should verify identical pin configurations, isolation ratings, and current transfer ratios to ensure functional equivalence without circuit redesign.
