EL817S1(D)(TU)-F

Overview

The EL817S1(D)(TU)-F is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode and an NPN phototransistor in a surface-mount SOP-4 package. Key electrical specifications include a collector-emitter voltage of 35V, a maximum forward current of 60mA, and a collector current of 50mA. The device provides an isolation voltage of 5kVrms and operates within a temperature range of -55°C to +110°C. Typical rise and fall times are 18µs, with a current transfer ratio ranging from 300% to 600%.

Feature Summary

Provides galvanic isolation between input and output circuits via optical transmission
Utilizes an NPN phototransistor for digital signal switching applications
Designed for surface-mount assembly in compact electronic systems

Applications

Digital logic signal transmission and level shifting
Power supply control and switching circuits
Electrical insulation between separate circuit systems

Procurement Notes

Verify the specific suffix (D) against the manufacturer's datasheet to confirm the exact Current Transfer Ratio binning, as this parameter varies significantly across different product grades within the same package type. Ensure the ordering code matches the required tape-and-reel quantity and packaging format specified in the official documentation before finalizing procurement.

Selection Notes

Select this component when high isolation voltage is required for low-speed digital signal interfacing. The 5kVrms rating supports safety standards for mains-connected equipment. Consider the 18µs switching speed limitations compared to faster optocouplers if high-frequency data transmission is necessary. Verify that the 35V output voltage rating meets the load requirements of the target application circuit.

Part Context

This part belongs to the EL817 series of transistor output optocouplers, widely used for general-purpose isolation. The S1 designation typically indicates a specific lead form or spacing variant suitable for surface mount technology. The TU suffix denotes tape and reel packaging, facilitating automated assembly processes in high-volume manufacturing environments.
