Overview
The EL816(S1)(B)(TD)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features a high isolation voltage of 5000 Vrms between input and output circuits, with a creepage distance exceeding 7.62 mm. The device utilizes an NPN phototransistor output capable of handling a maximum collector-emitter breakdown voltage of 80 V and a continuous collector current of 50 mA. It operates within a temperature range of -55 °C to +110 °C. The component is RoHS compliant and carries UL and VDE approvals for safety standards.
Feature Summary
- High isolation voltage capability of 5000 Vrms between input and output
- Creepage distance greater than 7.62 mm for enhanced safety
- Wide operating temperature range extending up to +110 °C
- Compliant with RoHS directives and approved by UL and VDE
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission in noisy electrical environments
- Power supply feedback loops for circuit protection
Procurement Notes
Verify the specific suffix configuration against the manufacturer's datasheet to ensure correct packaging and compliance status. Confirm that the procurement source provides official documentation for UL and VDE approvals. Ensure the component matches the required surface mount package type and lead-free specifications before finalizing orders.
Selection Notes
Select this component when high isolation voltage and wide temperature operation are critical. The NPN phototransistor output suits digital signal switching applications. Verify that the current transfer ratio meets the system requirements at the intended operating current. Ensure the surface mount footprint aligns with the PCB design constraints.
Part Context
This part belongs to the EL816 series of transistor output optocouplers from Everlight. The series is designed for general-purpose isolation applications. Variations in the suffix indicate differences in packaging, such as tape and reel options, or specific compliance certifications. The core electrical characteristics remain consistent across the family variants.
Replacement Considerations
Compatible substitutes include other 4-pin SMD transistor optocouplers with similar isolation ratings and pin configurations. Verify pinout compatibility and electrical parameters such as CTR and breakdown voltage before substitution.
