Overview
The EL814S1(A)(TB) is a single-channel optocoupler featuring an AC-input configuration with two infrared-emitting diodes connected in inverse parallel, optically coupled to an NPN phototransistor detector. It provides high isolation voltage of 5000 Vrms between input and output circuits. The device supports a collector-emitter breakdown voltage of 80V and operates within a wide temperature range from -55°C to 110°C. It is housed in a surface-mount package designed for compact circuit layouts.
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 demanding environments
- Compact surface-mount packaging for space-constrained designs
Applications
- Digital logic signal transmission and level shifting
- Power supply control and switching circuits
- Electrical insulation isolation between system components
- Impedance transformation between different circuit stages
Procurement Notes
Verify the specific suffix designation against official Everlight documentation to confirm package type and compliance status. Ensure the component matches the required isolation voltage ratings for your safety standards. Check for RoHS compliance markers on the datasheet. Confirm availability status as distribution channels may vary. Validate pinout compatibility with your PCB footprint before ordering.
Selection Notes
Select this component when AC input detection is required without external rectification. The dual-diode input structure simplifies circuit design for bidirectional signal isolation. Consider the 5000 Vrms isolation rating for high-voltage separation needs. Evaluate the surface-mount form factor against assembly constraints. Verify thermal performance within the specified -55°C to 110°C operational window.
Part Context
This part belongs to the EL814 series of transistor-output optocouplers manufactured by Everlight Electronics. The series includes various package options such as DIP and surface-mount configurations. These devices are widely used for general-purpose isolation applications requiring reliable signal transfer across isolated boundaries while maintaining electrical safety standards.
Replacement Considerations
Equivalent parts include other AC-input optocouplers with similar isolation ratings and phototransistor outputs. Verify pinout compatibility and current transfer ratio specifications when substituting. Ensure replacement components meet the same voltage and temperature requirements.
