EL814S(A)(TA)-V

Overview

The EL814S(A)(TA)-V is a single-channel optocoupler featuring an AC input phototransistor output configuration. It integrates 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 circuits. It operates within a wide temperature range from -55°C to 110°C and supports a maximum collector-emitter voltage of 80V. The component is housed in a compact 4-pin DIP package.

Feature Summary

• AC input response capability due to dual inverse-parallel infrared LEDs
• High electrical isolation voltage between input and output sections
• Wide operating temperature range suitable for extreme conditions
• Compact dual-in-line package design

Applications

• AC signal isolation interfaces
• Solid-state relay driver circuits
• Microcontroller interface with AC mains monitoring
• Industrial control system isolation

Procurement Notes

Verify the specific suffix designation against the manufacturer's current datasheet to ensure compatibility with required packaging and compliance standards. Confirm that the AC input configuration aligns with the target circuit design requirements before procurement.

Selection Notes

Select this component when AC signal detection without external rectification is required. Ensure the application voltage does not exceed the 80V collector-emitter rating. Verify that the 5000 Vrms isolation level meets the safety requirements of the target equipment.

Part Context

This part belongs to the EL814 series of optocouplers manufactured by Everlight Electronics. The series is characterized by its unique AC input structure, distinguishing it from standard DC-input optocouplers. It is widely used in applications requiring direct AC signal coupling.

Replacement Considerations

Equivalent parts include EL814S1(A)(TA)-V and EL814S(A)(TB)-VF. Verify pinout compatibility and isolation voltage ratings when substituting.
