EL816(C)-VG

Overview

The EL816(C)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode optically coupled to a phototransistor detector within a compact 4-pin DIP package. The device provides high isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 80V, a continuous collector current of 50mA, and a forward current rating of 60mA. The unit operates across a temperature range of -55°C to +110°C and complies with RoHS standards.

Feature Summary

• High isolation voltage capability of 5000 Vrms between input and output sides
• Compact 4-pin dual in-line package design suitable for surface mount or through-hole applications
• Wide operating temperature range extending up to +110°C for robust performance
• Compliant with lead-free and RoHS directives for environmental safety

Applications

• General purpose signal isolation in industrial control systems
• Switching power supply feedback loops
• Microcontroller interface circuits requiring galvanic isolation
• Solid-state relay driver circuits

Procurement Notes

Verify the specific suffix VG against the manufacturer's official datasheet to confirm pinout configuration and packaging variant. Ensure compliance requirements such as UL and VDE approvals match the project specifications. Confirm availability of the 4-pin DIP format and check for any recent lifecycle status changes directly from Everlight Electronics documentation before finalizing procurement orders.

Selection Notes

Select this component when a standard transistor output optocoupler with 5000V isolation is required. The 50mA collector current rating suits moderate load switching applications. Consider the 80V collector-emitter voltage limit for circuit design margins. Verify that the DIP-4 package fits the available PCB footprint constraints compared to SMD alternatives in the same series.

Part Context

This part belongs to the EL816 series of phototransistor optocouplers produced by Everlight Electronics. The series typically offers various isolation ratings and package options including DIP and SMD configurations. The EL816 family is widely recognized for general-purpose isolation tasks in electronic designs requiring reliable signal transmission across isolated boundaries.

Replacement Considerations

Equivalent parts include the EL817 series or generic PC817 variants which share similar pinouts and electrical characteristics. Verify that substitute components meet the 5000V isolation requirement and 50mA current handling capacity. Check for matching CTR ranges and operating temperature specifications to ensure circuit compatibility.
