EL817S1(C)(TU)-F

Overview

The EL817S1(C)(TU)-F is a transistor output optocoupler manufactured by Everlight Electronics. It features a single channel with DC input and an NPN phototransistor output. Key electrical parameters include a collector-emitter saturation voltage of 100mV at 1mA/20mA, a forward voltage of 1.2V, and a reverse voltage of 6V. The device supports a maximum collector current of 50mA and a forward current of 60mA. It offers a high isolation voltage of 5kVrms and operates within a temperature range of -55°C to +110°C. The total power dissipation is rated at 200mW.

Feature Summary

Provides electrical isolation between input and output circuits via infrared light transmission.
Features a compact surface-mount SOP-4 package for efficient PCB integration.
Ensures signal integrity through stable current transfer ratio performance.

Applications

Industrial control systems such as PLCs and servo drives
Power management circuits including switch-mode power supplies
Communication equipment requiring signal isolation

Procurement Notes

Verify the specific suffix codes against official Everlight documentation to confirm pinout compatibility and packaging type. Ensure that the requested variant matches the required isolation voltage and thermal specifications for the target application environment. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when high isolation voltage and compact SMD form factor are required. Consider the CTR range and switching times for signal fidelity needs. Evaluate thermal management requirements given the 200mW power dissipation rating. Compare alternative packages if space constraints differ from the standard SOP-4 footprint.

Part Context

This part belongs to the EL817 series of transistor output optocouplers. It is designed for general-purpose isolation applications where reliable signal transmission across isolated barriers is critical. The series is widely used in industrial and consumer electronics for noise immunity and safety compliance.
