EL847S-V

Overview

The EL847S-V is a quad transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features four independent channels within a single 16-SMD package, providing electrical isolation with a voltage rating of 5000Vrms. The device offers a minimum current transfer ratio of 50% at a forward current of 5mA. It operates across an extended temperature range from -55°C to 110°C and utilizes surface mount technology for integration into electronic circuits.

Feature Summary

• Quad channel configuration for multi-signal isolation
• High voltage isolation capability
• Extended operating temperature range

Applications

• Industrial control systems requiring multi-channel isolation
• Signal transmission in noisy environments
• Power supply feedback loops

Procurement Notes

Verify the specific suffix and packaging type when ordering, as availability may vary by distributor. Confirm that the 16-SMD package dimensions match your PCB footprint requirements. Ensure the 5000Vrms isolation rating meets the safety standards of your target application. Check for any recent product change notifications regarding material or process updates.

Selection Notes

Select this component when multiple isolated channels are required in a compact surface-mount form factor. The high isolation voltage makes it suitable for applications involving significant potential differences between input and output sides. Consider the thermal management capabilities given the wide operating temperature range and the density of four channels in one package.

Part Context

This part belongs to Everlight's family of transistor output optocouplers designed for general-purpose isolation. The quad configuration distinguishes it from single-channel variants, offering space savings in designs requiring multiple isolated signals. It serves as a solution for separating digital or analog signals while maintaining electrical safety barriers.

Replacement Considerations

Direct substitutes include other quad transistor output optocouplers with similar isolation ratings and pin configurations. Verify compatibility with existing circuit designs before swapping components.
