EL814S1(A)(TA)

Overview

The EL814S1(A)(TA) is a single-channel optocoupler featuring an infrared emitting diode and an NPN phototransistor. It utilizes AC input capability via inverse-parallel LED configuration, providing electrical isolation with a maximum voltage of 5000 Vrms. The device supports a collector-emitter breakdown voltage of 80V and operates within a temperature range of -55°C to 110°C. Key electrical parameters include a typical forward voltage of 1.2V, a maximum DC forward current of 60mA, and a current transfer ratio ranging from 50% to 150%.

Feature Summary

AC input response capability due to inverse-parallel infrared LED structure.
High isolation voltage between input and output terminals.
Wide operating temperature range suitable for industrial environments.
Compact surface-mount package design.

Applications

Digital logic signal transmission and conversion.
Power supply control and switching circuits.
Electrical insulation isolation between circuits and systems.

Procurement Notes

Verify the specific suffix (TA) against official Everlight documentation to confirm the exact tape-and-reel packaging specifications and RoHS compliance status. Ensure the component matches the required surface-mount footprint dimensions before integration into the PCB layout.

Selection Notes

Select this component when AC input compatibility is required alongside standard transistor output isolation. Compare the 5000 Vrms isolation rating and 80V collector-emitter voltage against system requirements. Consider the -55°C to 110°C operating range for environmental suitability.

Part Context

This part belongs to the EL814 series, which consists of devices combining infrared LEDs and phototransistors in a 4-pin DIP or SMD package. The series is designed for general-purpose isolation applications requiring high reliability and compact form factors.

Replacement Considerations

Consult official Everlight datasheets for direct pin-compatible substitutes within the EL814 family. Verify equivalent isolation ratings and current transfer ratios before substituting with components from other manufacturers.
