EL814S(TA)

Overview

The EL814S(TA) is a surface-mount AC input-transistor output optocoupler from Everlight Electronics. It features two infrared emitting diodes connected in inverse parallel, optically coupled to a phototransistor detector. The device provides high isolation voltage of 5000 Vrms and supports a wide operating temperature range from -55°C to 110°C. Key electrical parameters include a collector-emitter breakdown voltage of 80V, a typical forward voltage of 1.2V, and a maximum forward current of 60mA. The component is housed in a compact 4-pin SMD package compliant with RoHS standards.

Feature Summary

AC input response capability via dual inverse-parallel infrared LEDs
High isolation voltage between input and output circuits
Wide operating temperature range suitable for harsh environments

Applications

Solid-state relay driver circuits
Switching power supply feedback loops
Microcontroller interface isolation

Procurement Notes

Verify the specific suffix (TA) against the manufacturer datasheet to confirm pinout orientation and tape-and-reel specifications. Ensure the procurement source provides valid UL and VDE certification documentation. Confirm that the component meets current RoHS compliance requirements before finalizing orders.

Selection Notes

Select this component when AC signal detection or direct mains interfacing is required without additional rectification circuitry. The dual-diode input structure simplifies design by handling both positive and negative half-cycles. Consider the 80V collector-emitter voltage rating for low-voltage logic level switching applications requiring galvanic isolation.

Part Context

The EL814 series consists of devices with two infrared emitting diodes connected in inverse parallel, optically coupled to a phototransistor detector. Packaged in a 4-pin DIP or SMD format, these components are designed for AC input applications. The series is recognized by major safety agencies including UL, VDE, and CSA.
