ELD211(TA)

Overview

The ELD211(TA) is a dual-channel phototransistor output optocoupler manufactured by Everlight Electronics. It features an isolation voltage of 3750 Vrms and operates within a temperature range of -55°C to 110°C. The device utilizes an NPN phototransistor output configuration with a maximum output voltage of 80V. Packaged in an 8-pin SOP format, it is designed for surface-mount applications requiring high insulation performance.

Feature Summary

• Dual-channel architecture providing independent signal isolation paths
• High insulation capability rated at 3750 Vrms for safety compliance
• Extended operating temperature range supporting harsh environments

Applications

• Industrial control systems requiring galvanic isolation
• Communication equipment interface circuits
• Power supply feedback loops

Procurement Notes

Verify the specific suffix designation against official Everlight documentation to confirm exact packaging and handling specifications. Ensure compatibility with RoHS and REACH regulatory standards required for your region. Confirm moisture sensitivity levels prior to soldering processes to prevent package damage during assembly.

Selection Notes

Select this component when dual-channel isolation is necessary within a compact surface-mount footprint. Consider the 80V output voltage limit and NPN configuration for circuit design compatibility. Evaluate thermal management requirements given the wide operating temperature range and SOP package constraints.

Part Context

This part belongs to Everlight’s transistor output optocoupler series, designed for general-purpose isolation tasks. The SOP-8 package offers a balance between pin count and board space efficiency compared to larger DIP alternatives.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic equivalents may differ in isolation voltage or CTR specifications.
