ELD206(TA)-V

Overview

The ELD206(TA)-V is a dual-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features an isolation voltage of 3750 Vrms and operates within a temperature range of -55°C to 110°C. The device utilizes an 8-SOP surface-mount package with a width of 3.90mm. Key electrical parameters include a typical forward voltage of 1.2V, a maximum collector-emitter saturation voltage of 400mV, and rise/fall times of 1.6µs and 2.2µs respectively. The input type is DC, and the output consists of NPN phototransistors.

Feature Summary

• Dual-channel configuration for independent signal isolation
• High insulation voltage capability for safety separation
• Wide operating temperature range for harsh environments
• Surface-mount packaging for automated assembly

Applications

• Industrial control systems requiring galvanic isolation
• Signal transmission between microcontrollers and power circuits
• Noise immunity in digital communication interfaces

Procurement Notes

Verify the specific suffix (TA) against official Everlight documentation to confirm pinout and internal configuration. Ensure the 8-SOP package dimensions match the target PCB footprint. Confirm that the 3750 Vrms isolation rating meets the safety requirements of the end application. Check for RoHS compliance status if required by regulatory standards.

Selection Notes

Select this component when dual-channel isolation is required in a compact surface-mount form factor. Consider the 1.6µs/2.2µs switching speeds for moderate data rate applications. Evaluate the 400mV Vce(sat) for low-voltage logic compatibility on the output side. Ensure the input current limits are respected when designing the driving circuitry.

Part Context

This part belongs to the ELD206 series of transistor output optocouplers from Everlight. The series offers various channel counts and package options. The TA variant specifically denotes the dual-channel configuration in an 8-pin SOP package. This family is designed for general-purpose isolation tasks where cost-effectiveness and reliability are prioritized.

Replacement Considerations

Direct substitutes may include other dual-channel transistor optocouplers with similar isolation ratings and package types. Verify pin-to-pin compatibility before substitution. Alternative models from different manufacturers should be evaluated based on matching electrical characteristics and thermal performance.
