EL211(TA)-V

Overview

The EL211(TA)-V is a single-channel optocoupler manufactured by Everlight Electronics Co Ltd. It features an infrared emitting diode as the input and an NPN phototransistor with a base terminal for enhanced switching speed as the output. The device is housed in an 8-pin SOP package designed for surface mount technology. Key electrical specifications include a minimum current transfer ratio of 20% at a forward current of 10mA and an isolation voltage rating of 3750 Vrms.

Feature Summary

• Integrates an NPN phototransistor with a dedicated base terminal to improve switching performance compared to standard configurations.
• Provides high-voltage electrical isolation between input and output circuits via a robust dielectric barrier.
• Utilizes an 8-pin SOP surface-mount package to facilitate automated assembly and compact circuit board layouts.

Applications

• Signal isolation in industrial control systems
• Interface circuits for microcontrollers and logic devices
• Power supply feedback loops

Procurement Notes

Verify the specific suffix TA-V against the manufacturer's latest datasheet to confirm pinout compatibility and tape-and-reel packaging requirements. Ensure that the procurement source provides valid RoHS compliance documentation and original manufacturer traceability records to guarantee component authenticity and reliability.

Selection Notes

Select this component when a transistor output optocoupler requires a base terminal for faster turn-off times or improved noise immunity. Confirm that the required isolation voltage meets or exceeds the system's safety standards and that the SOP-8 footprint aligns with the existing PCB design constraints.

Part Context

This part belongs to the EL211 family of phototransistor output optocouplers from Everlight. The TA-V suffix typically denotes specific packaging variations, such as tape-and-reel orientation or moisture sensitivity handling, rather than changes to the internal semiconductor structure or electrical function.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided reference data. Verify pin-to-pin compatibility and electrical parameter equivalence before considering alternative manufacturers.
