EL814S1(A)(TB)-V

Overview

The EL814S1(A)(TB)-V is a single-channel optocoupler featuring an AC/DC input phototransistor output. It integrates two inverse-parallel infrared LEDs coupled to a phototransistor detector in a surface-mount package. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a typical forward voltage of 1.2 V, and a maximum DC forward current of 60 mA. The device offers a minimum isolation voltage of 5000 Vrms and operates within a temperature range of -55°C to 110°C.

Feature Summary

Dual inverse-parallel infrared LED configuration enables direct AC input signal processing without external rectification.

Applications

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

Procurement Notes

Verify the specific suffix 'V' confirms the surface-mount tape-and-reel packaging format. Confirm RoHS compliance status and UL/VDE recognition numbers match project safety requirements. Check for any recent lifecycle changes or obsolescence notices from Everlight Electronics before finalizing procurement plans.

Selection Notes

Select this component when AC input detection is required directly from the optocoupler input side. Ensure the 80 V collector-emitter voltage rating exceeds the maximum output circuit voltage. Verify that the 5000 Vrms isolation barrier meets the specific safety standards required for the application environment.

Part Context

This part belongs to the EL814 series of phototransistor output optocouplers manufactured by Everlight Electronics. The series is characterized by high isolation voltage capabilities and compact packaging options suitable for modern surface-mount assembly processes.

Replacement Considerations

Equivalent parts may include other AC-input capable optocouplers with similar 5000 Vrms isolation and NPN transistor outputs. Verify pinout compatibility and CTR specifications before substitution.
