EL814(A)-V

Overview

The EL814(A)-V is a single-channel optocoupler featuring an AC input configuration with two infrared emitting diodes connected in inverse parallel, optically coupled to a phototransistor detector. It provides high isolation voltage of 5000 Vrms and supports a collector-emitter breakdown voltage of 80 V. The device operates within a temperature range of -55°C to 110°C, with a maximum forward current of 60 mA and typical rise/fall times of 7 µs and 11 µs respectively.

Feature Summary

• AC input response capability due to dual inverse-parallel infrared LEDs
• High isolation voltage between input and output terminals
• Wide operating temperature range suitable for industrial environments

Applications

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

Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to ensure correct package type and compliance status. Confirm that the requested variant matches the required isolation voltage and current transfer ratio specifications for the intended application circuit design.

Selection Notes

Select this component when AC signal detection or bidirectional LED driving is required within an isolated interface. Ensure the system voltage does not exceed the 80 V collector-emitter rating and that the thermal management accommodates the specified operating temperature limits.

Part Context

This part belongs to the EL814 series manufactured by Everlight Electronics. The series utilizes a phototransistor output architecture paired with an AC-compatible input structure, designed for robust signal isolation in compact DIP packages.

Replacement Considerations

Cross-reference with other EL814 series variants such as EL814S1(A)(TB)-V for surface mount alternatives. Verify pinout compatibility and electrical parameter equivalence before substitution.
