Overview
The EL814S(A)(TD)-V is a single-channel optocoupler featuring an AC/DC input phototransistor output. It integrates two infrared emitting diodes connected in inverse parallel with a phototransistor detector. 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 provides high isolation voltage of 5000 Vrms and operates within a temperature range of -55°C to 110°C.
Feature Summary
- AC input response capability due to inverse parallel infrared LED configuration
- High isolation voltage between input and output channels
- Wide operating temperature range suitable for industrial environments
Applications
- Digital logic transmission and conversion
- Power control and switching circuits
- Electrical insulation isolation between circuits and systems
Procurement Notes
Verify the specific suffix (TD) against the manufacturer's official datasheet to confirm package type and compliance status. Ensure the ordering code matches the required surface mount or through-hole configuration. Cross-reference the revision level to guarantee compatibility with existing design specifications.
Selection Notes
Select this component when AC signal detection is required at the input stage without additional rectification circuitry. The inverse parallel LED structure allows direct coupling of alternating signals. Verify that the 80 V output voltage rating meets the load requirements and that the 5000 Vrms isolation satisfies safety standards for the application.
Part Context
This part belongs to the EL814 series from Everlight Electronics. The series consists of devices with two infrared emitting diodes optically coupled to a phototransistor detector. Variations in the suffix typically denote package style or tape-and-reel packaging options while maintaining core electrical characteristics.
Replacement Considerations
Compatible substitutes include other AC-input transistor-output optocouplers with similar isolation ratings and pin configurations. Verify pinout compatibility and thermal performance before substitution.
