EL817(M)(C)-VG

Overview

The EL817(M)(C)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with an NPN phototransistor detector, providing electrical isolation between input and output circuits. The device features a high isolation voltage of 5000 Vrms and operates within a temperature range of -55°C to +110°C. It is available in a surface-mount DIP-4 package configuration compliant with RoHS standards.

Feature Summary

• Provides galvanic isolation via optical coupling between input and output sections
• Utilizes an NPN phototransistor for DC signal transmission
• Complies with international safety standards including UL, VDE, and SEMKO approvals

Applications

• Signal isolation in industrial control systems
• Power supply feedback loops
• Microcontroller interface circuits

Procurement Notes

Verify the specific suffix VG against the manufacturer's current datasheet to confirm package type and compliance status. Confirm availability as distribution channels may list this component as limited stock or obsolete depending on regional inventory updates.

Selection Notes

Select this component when surface-mount assembly is required for standard 817-series isolation applications. Ensure the design accommodates the specific CTR range and switching times defined in the official electrical characteristics table.

Part Context

This part belongs to the EL817 series of optocouplers, which are widely used for general-purpose isolation. The EL817 family typically offers variants in both through-hole DIP and surface-mount packages, maintaining consistent electrical performance across form factors.

Replacement Considerations

Direct substitutes include other EL817 series variants from Everlight such as EL817(S)(C)-V or generic equivalents like PC817, provided pinout and isolation ratings match.
