EL816(S1)(B)(TU)-V

Overview

The EL816(S1)(B)(TU)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features a surface-mount DIP-4 package with RoHS compliance and UL/VDE approvals. Key electrical parameters include a maximum collector-emitter breakdown voltage of 80 V, a nominal current transfer ratio of 100%, and a maximum forward current of 0.05 A. The device supports an operating temperature range from -55 °C to +110 °C and provides high isolation voltage between input and output.

Feature Summary

High isolation voltage capability between input and output circuits
Compact surface-mount design suitable for automated assembly
Wide operating temperature range for industrial environments

Applications

Signal isolation in digital communication interfaces
Switching power supply feedback loops
Microcontroller input/output isolation

Procurement Notes

Verify the specific suffix codes against official Everlight documentation to confirm pinout configuration and packaging type. Ensure the component meets required safety certifications such as UL or VDE for the target application. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement specifications.

Selection Notes

Select this component when a compact surface-mount phototransistor coupler is required for galvanic isolation. Consider the 80 V collector-emitter breakdown voltage and 100% CTR for standard logic interface applications. Verify thermal management requirements given the wide operating temperature range and surface-mount form factor.

Part Context

This part belongs to the EL816 series of transistor output optocouplers. The series is designed for general-purpose signal isolation. The specific model indicates a surface-mount variant with defined electrical characteristics and safety approvals. It serves as a standard solution for isolating low-voltage control signals from higher voltage loads.
