Overview
The EL816(S1)(B)(TB)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output and provides high isolation voltage of 5000 Vrms between input and output circuits. The device supports surface mount installation in a compact SMD package. Key electrical parameters include a collector-emitter breakdown voltage of 80 V minimum, maximum forward current of 60 mA, and saturation voltage of 200 mV. It operates within a temperature range of -55°C to +110°C and complies with RoHS standards.
Feature Summary
- High isolation voltage capability for secure signal transmission
- Compact surface mount design suitable for space-constrained applications
- Wide operating temperature range for diverse environmental conditions
Applications
- Secure data transmission systems
- Signal isolation in industrial control circuits
- Protection interfaces in electronic equipment
Procurement Notes
Verify the specific suffix configuration against official Everlight documentation to ensure correct packaging and compliance status. Confirm that the requested variant matches the required isolation voltage and mounting type specifications for the target application. Cross-reference part numbers with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when high isolation voltage and compact surface mount form factor are required. Ensure the NPN phototransistor output aligns with the receiving circuit requirements. Verify thermal management capabilities given the wide operating temperature range and potential power dissipation in saturated states.
Part Context
This part belongs to the EL816 series of transistor output optocouplers from Everlight. The series is designed for general-purpose isolation applications requiring reliable signal transfer between isolated circuits. Variants differ primarily in packaging, lead finish, and compliance certifications while maintaining core electrical performance characteristics.
Replacement Considerations
Direct substitutes may include other EL816 variants with compatible pinouts and electrical ratings. Verify that alternative parts meet the same 5000 Vrms isolation requirement and surface mount package dimensions. Check CTR ranges and saturation voltages to ensure functional equivalence in the specific circuit design.
