Overview
The EL817(S)(C)(TU)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with an NPN phototransistor detector in a compact surface-mount package. The device provides high isolation voltage of 5000 Vrms between input and output circuits. It supports a collector-emitter breakdown voltage of 35 V and a maximum continuous collector current of 50 mA. The component operates within a temperature range of -55°C to +110°C and features a nominal current transfer ratio of 200%.
Feature Summary
- High isolation voltage capability of 5000 Vrms for reliable signal transmission across isolated domains
- Compact small outline surface-mount package design suitable for automated assembly processes
- RoHS compliant construction ensuring environmental safety standards are met
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission in microprocessor-based circuits
- Power supply feedback loop isolation
Procurement Notes
Verify the specific suffix VG against the manufacturer's official datasheet to confirm exact packaging and compliance details. Ensure the component meets all required insulation and thermal specifications for the target application environment before integration.
Selection Notes
Select this component when a surface-mount solution is required for single-channel isolation. Consider the 5000 Vrms rating for high-voltage separation needs. Verify that the NPN phototransistor output configuration aligns with the receiving circuit requirements.
Part Context
This part belongs to the EL817 series, which consists of infrared emitting diodes optically coupled to phototransistor detectors. The series is available in both DIP and SMD packages, offering versatile options for various PCB layout constraints while maintaining consistent electrical performance characteristics.
Replacement Considerations
Cross-reference with other EL817 variants such as EL817(S)(C)(TU) or EL817(S1)(C)(TU). Verify pinout compatibility and electrical parameter equivalence before substitution.
