Overview
The EL817(S1)(TD)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode and an NPN phototransistor to provide 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. It utilizes a surface-mount package configuration suitable for automated assembly processes.
Feature Summary
- Provides galvanic isolation via optical coupling between input and output sides
- Features high insulation voltage capability for safety barrier applications
- Designed for surface-mount technology (SMD) integration
- Compliant with lead-free manufacturing standards
Applications
- Industrial control systems requiring signal isolation
- Power supply feedback loop isolation
- Communication equipment interface protection
Procurement Notes
Verify the specific suffix codes against official Everlight documentation to confirm pinout orientation, tape-and-reel specifications, and compliance certifications. Ensure the selected variant matches the required thermal management and mounting constraints for the target PCB design before finalizing procurement orders.
Selection Notes
Select this component when surface-mount isolation is required for low-speed digital or analog signal transmission. Consider the current transfer ratio limits and operating temperature range relative to the application environment. Verify that the package dimensions align with the available footprint on the printed circuit board layout.
Part Context
This part belongs to the EL817 series of optocouplers, which are widely used for general-purpose isolation tasks. The S1 designation typically indicates specific mechanical or performance characteristics within the family. The VG suffix denotes specific packaging or regulatory compliance attributes defined by the manufacturer for this particular ordering code.
Replacement Considerations
Cross-reference with other EL817 variants from Everlight or equivalent transistor-output optocouplers from other manufacturers. Ensure compatibility regarding pin configuration, isolation voltage ratings, and package dimensions before substituting.
