EL817(C)-VG

Overview

The EL817(C)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with an NPN phototransistor detector to provide electrical isolation. The device features a maximum insulation voltage of 5000 Vrms and supports a collector-emitter breakdown voltage of 35 V. It operates within a temperature range of -55°C to +110°C, ensuring reliability in demanding environments.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits using optical coupling technology.
• Utilizes an NPN phototransistor output configuration for reliable DC signal transmission.
• Compliant with RoHS standards and free from halogen content.

Applications

• Industrial control systems requiring signal isolation
• Automation equipment interfaces
• Noise-sensitive circuit protection

Procurement Notes

Verify the specific suffix designation against official Everlight documentation to confirm package type and compliance status. Confirm availability as distribution channels may vary. Ensure the component meets all required safety certifications for the target application before integration.

Selection Notes

Select this component when a standard DIP-4 form factor is required for through-hole mounting. Verify that the 5000 Vrms isolation rating and 35 V output voltage meet the system's electrical requirements. Consider thermal management capabilities given the wide operating temperature range.

Part Context

This part belongs to the EL817 series of optocouplers, which are widely used for general-purpose isolation. The VG suffix typically denotes specific packaging or compliance variations within the Everlight portfolio. It serves as a fundamental building block for digital signal isolation in electronic designs.

Replacement Considerations

Cross-reference with other EL817 variants such as EL817(S)(C) or EL817(S1)(C) for pin-compatible alternatives. Verify that substitute parts maintain identical isolation voltage and current transfer ratio specifications to ensure functional equivalence.
