Overview
The EL816S2(A)(TU)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with a phototransistor detector in a compact 4-SMD, Gull Wing package. The device provides electrical isolation with an insulation voltage of 5kV and supports a collector-emitter voltage of 80V. Designed for surface mount applications, it offers reliable signal transmission between isolated circuits while maintaining high safety standards.
Feature Summary
- Integrates an infrared LED coupled to a phototransistor for optical signal transmission
- Provides high-voltage isolation capability suitable for sensitive circuit protection
- Utilizes a compact surface-mount package design for automated assembly
Applications
- Signal isolation in industrial control systems
- Interface circuits for microcontrollers and logic devices
- Power supply feedback loops requiring galvanic isolation
Procurement Notes
Verify the specific suffix (A)(TU)-V against official Everlight documentation to confirm pinout and packaging configuration. Ensure compliance with ROHS3 requirements and MSL 1 rating as stated in public component records. Confirm that the Tape & Reel packaging matches your manufacturing equipment specifications before finalizing procurement orders.
Selection Notes
Select this component when a single-channel transistor output is required for low-speed digital isolation. The 5kV insulation rating makes it suitable for applications demanding significant potential difference separation. Consider the 4-SMD form factor for space-constrained printed circuit board layouts where through-hole mounting is not feasible.
Part Context
This part belongs to the EL816 series of optocouplers from Everlight Electronics. The series typically features infrared emitters paired with silicon phototransistors. Variants within the series differ primarily in packaging styles and specific electrical parameter tolerances, but share the fundamental architecture of optical coupling for electrical isolation purposes.
Replacement Considerations
Publicly confirmed substitute part numbers are not explicitly listed in the provided source material. Cross-referencing with generic EL816 equivalents requires verification of exact pin configurations and electrical limits against the original datasheet to ensure functional compatibility.
