Overview
The EL814S1(A)(TD) is a single-channel optocoupler manufactured by Everlight Electronics. It features an AC/DC input type with a phototransistor output, housed in a surface-mount SMD-4 package. The device provides high isolation voltage of 5000Vrms between input and output circuits. Key electrical parameters include a typical forward voltage of 1.2V, maximum DC forward current of 60mA, and a maximum output voltage of 80V. The current transfer ratio ranges from 50% to 150%. It operates within a temperature range of -55°C to 110°C.
Feature Summary
- Dual infrared emitting diodes connected in inverse parallel enable AC input response capability alongside standard DC operation.
- High isolation voltage rating ensures robust electrical insulation between input and output sections for safety compliance.
- Compact surface-mount packaging facilitates automated assembly and space-constrained circuit board designs.
Applications
- Digital logic signal transmission and level shifting
- Power supply control and switching circuits
- Electrical isolation between system components
Procurement Notes
Verify the specific suffix (TD) against the manufacturer's latest datasheet to confirm pinout configuration and tape-and-reel specifications. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required by project regulations.
Selection Notes
Select this component when AC input detection is required in a compact surface-mount form factor. The dual-diode input structure simplifies circuit design for bidirectional signal isolation. Verify that the 80V collector-emitter voltage meets the load requirements. Consider thermal management within the specified operating temperature range during high-duty cycle applications.
Part Context
This device belongs to the EL814 series of transistor output optocouplers. The series is designed for general-purpose isolation applications requiring high reliability. The specific model variant indicates a surface-mount package configuration distinct from through-hole DIP versions found in the same product family.
Replacement Considerations
Equivalent parts may include other AC-input capable phototransistor optocouplers with similar isolation ratings and SMD-4 packages. Verify pin compatibility and current transfer ratio characteristics before substitution. Consult manufacturer cross-reference guides for confirmed alternatives.
