EL208(TA)

Overview

The EL208(TA) is a single-channel optoisolator manufactured by Everlight Electronics Co Ltd. It features an NPN phototransistor output with a base terminal, housed in an 8-SOP package. The device provides an insulation voltage of 3750 Vrms and is designed for surface mount applications. It is classified as a transistor output optocoupler and exhibits moisture sensitivity.

Feature Summary

• Integrates an infrared emitting diode with an NPN phototransistor having a base connection for improved switching speed and linearity.

Applications

• Signal isolation in industrial control systems
• Interface between microprocessors and high-voltage circuits
• Switching power supply feedback loops

Procurement Notes

Verify the specific suffix designation against official Everlight documentation to confirm pinout and electrical characteristics. Ensure compliance with RoHS directives and check moisture sensitivity level requirements for storage and handling prior to assembly.

Selection Notes

Select this component when galvanic isolation is required between low-voltage logic and higher voltage loads. The base output allows for faster response times compared to standard phototransistors. Confirm the 8-SOP package fits the available PCB footprint and thermal constraints.

Part Context

This part belongs to Everlight's family of transistor output optocouplers. It serves as a standard solution for electrical isolation in compact electronic designs where space efficiency and reliable signal transmission across potential barriers are critical requirements.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify that any substitute maintains the same 3750 Vrms insulation rating and 8-SOP physical dimensions to ensure board compatibility.
