Overview
The EL816(S1)(Y)(TA) is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with an NPN phototransistor detector, providing electrical isolation between input and output circuits. The device features a high isolation voltage of 5000 Vrms and operates within a temperature range of -55°C to +110°C. Key electrical parameters include a collector-emitter breakdown voltage of 80V minimum, a maximum forward current of 60mA, and a typical rise/fall time of 4µs/3µs. The component is housed in a compact 4-SMD (gull-wing) surface-mount package.
Feature Summary
- High isolation voltage capability for secure signal transmission
- Wide operating temperature range suitable for demanding environments
- Compact surface-mount packaging for space-constrained designs
Applications
- Secure data transmission systems requiring galvanic isolation
- Industrial control circuit protection interfaces
- Signal isolation in measurement instrumentation
Procurement Notes
Verify the specific suffix codes against official Everlight documentation to confirm pinout configuration and compliance status. Ensure the selected variant matches the required isolation voltage and thermal specifications for the target application environment before finalizing procurement.
Selection Notes
Select this component when high-voltage isolation is required in a small form factor. Consider the 60mA maximum forward current limit and 80V collector-emitter breakdown voltage when designing the driving and load circuits. Verify compatibility with surface-mount assembly processes due to the SMD package type.
Part Context
This part belongs to the EL816 series of transistor output optocouplers from Everlight Electronics. The series is designed for general-purpose isolation applications, offering reliable performance through optical coupling. The specific model indicates a surface-mount version with defined electrical characteristics distinct from through-hole variants.
Replacement Considerations
Cross-reference with other EL816 series variants such as EL816(S1)(X)(TA) or EL816(S)(TA)-FV for pin-compatible alternatives. Verify that substitute parts meet the same 5000Vrms isolation and temperature rating requirements.
