EL817(S1)(B)(TU)-G

Overview

The EL817(S1)(B)(TU)-G is a single-channel transistor-output optocoupler manufactured by Everlight Electronics Co Ltd. It features an infrared emitting diode optically coupled to an NPN phototransistor in a compact 4-SMD gull-wing package. The device provides high isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a collector-emitter breakdown voltage of 35 V, maximum forward current of 60 mA, and output current capability of 50 mA. The current transfer ratio (CTR) is binned at 130% to 260% when tested at IF = 5 mA and VCE = 5 V. Operating temperature range spans from -55 °C to +110 °C.

Feature Summary

High isolation voltage capability between input and output circuits
Compact surface-mount gull-wing package design
RoHS compliant and halogen-free construction

Applications

Signal transmission between circuits of different potentials
Interface between microprocessors and control circuits
Switching power supply feedback loops

Procurement Notes

Verify the specific CTR binning requirements against the datasheet specifications for the B suffix. Confirm that the S1 package dimensions match the target PCB footprint. Ensure compliance with RoHS and halogen-free standards if required by the end application. Check for any specific handling precautions related to the surface-mount technology during assembly processes.

Selection Notes

Select this component when a small form factor is required for signal isolation applications. The S1 package offers a smaller footprint compared to traditional DIP packages while maintaining similar electrical performance. Consider the CTR range of 130-260% for circuit gain calculations. Verify that the 5000 Vrms isolation rating meets the safety requirements of the system being designed.

Part Context

This part belongs to the EL817 series of transistor-output optocouplers produced by Everlight. The series includes various package options such as DIP and SMD variants. The EL817 family is widely used for general-purpose isolation tasks. The S1 designation indicates a specific surface-mount package configuration within this product line.
