EL814S(A)(TU)-V

Overview

The EL814S(A)(TU)-V is a surface-mount optocoupler from Everlight Electronics. It features an AC input configuration with two infrared emitting diodes connected in inverse parallel, optically coupled to a phototransistor detector. The device provides high isolation voltage of 5000 Vrms between input and output. Key electrical parameters include a collector-emitter breakdown voltage (VCEO) of 80 V minimum, a typical forward voltage (VF) of 1.2 V, and a maximum continuous forward current (IF) of 60 mA. The current transfer ratio (CTR) ranges from 50% to 150%. It operates within a temperature range of -55°C to +110°C and complies with RoHS standards.

Feature Summary

AC input response capability due to dual inverse-parallel infrared LEDs
High isolation voltage of 5000 Vrms for enhanced safety
Compact surface-mount package design suitable for automated assembly

Applications

AC mains detection circuits
Solid-state relay inputs
Microcontroller interface for AC signals

Procurement Notes

Verify the specific suffix against the manufacturer's latest datasheet to confirm pinout and packaging details. Ensure compliance with regional environmental regulations such as RoHS. Confirm that the surface-mount variant matches the intended PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when AC signal isolation is required in a compact form factor. The dual-diode input structure eliminates the need for external rectification components for AC applications. Verify that the 80 V collector-emitter voltage rating meets the load requirements of the downstream circuitry.

Part Context

This part belongs to the EL814 series of optocouplers manufactured by Everlight Electronics. The series includes various packages and configurations, with the S(A)(TU)-V designation indicating a specific surface-mount version. The series is widely used in industrial and consumer electronics for signal isolation.

Replacement Considerations

Check for direct replacements within the EL814 family or equivalent parts from other manufacturers offering similar AC input transistor output optocouplers with comparable isolation ratings and package dimensions.
