EL814S(TU)-V

Overview

The EL814S(TU)-V is a single-channel optocoupler manufactured by Everlight Electronics. It features an AC input configuration utilizing 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 complies with RoHS standards.

Feature Summary

• AC input response capability via dual inverse-parallel infrared LEDs
• High isolation voltage of 5000 Vrms between input and output
• Wide operating temperature range suitable for industrial environments

Applications

• AC mains detection circuits
• Solid-state relay driver interfaces
• Microcontroller isolation for AC power monitoring

Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm package type and compliance status. Ensure the ordering code matches the required isolation rating and lead-free specifications. Cross-reference official datasheets for exact pinout and thermal characteristics before finalizing procurement.

Selection Notes

Select this component when AC signal isolation is required without external rectification. The inverse-parallel LED structure simplifies circuit design for AC inputs. Verify that the phototransistor collector-emitter voltage rating meets the load requirements of the isolated side application.

Part Context

This part belongs to the EL814 series of optocouplers designed for general-purpose isolation. The 'S' suffix typically indicates surface mount packaging, while '(TU)' denotes tape and reel packaging. The series is recognized by major safety agencies including UL and VDE for insulation systems.

Replacement Considerations

Check for direct equivalents such as the EL814S1(A)(TU)-V or EL814S(A)(TB)-VF. Verify pin compatibility and electrical parameters like CTR and isolation voltage before substitution.
