Overview
The EL817(S1)(A)(TD)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output and provides high isolation voltage of 5000 Vrms between input and output circuits. The device utilizes a surface-mount SMD package configuration, specifically designed for tape and reel processing to facilitate automated assembly. Key electrical characteristics include a minimum current transfer ratio of 50% at a forward current of 5mA and collector-emitter voltage of 5V. The component operates within a temperature range of -55°C to 110°C and supports a maximum forward current of 50mA.
Feature Summary
- Provides galvanic isolation with high dielectric strength between input LED and output phototransistor
- Designed for surface-mount technology applications using tape and reel packaging
- Features compact dual-in-line style footprint adapted for SMD mounting processes
Applications
- Signal isolation in industrial control systems
- Interface circuits for microcontrollers and logic devices
- Power supply feedback loops requiring DC input isolation
Procurement Notes
Verify the specific suffix (S1)(A)(TD)-VG against the manufacturer datasheet to confirm lead bending type, CTR binning, and RoHS compliance status. Ensure the ordering quantity matches the tape and reel specifications provided in the official documentation. Confirm that the surface-mount footprint dimensions align with your PCB design requirements before finalizing procurement.
Selection Notes
Select this component when surface-mount assembly is required for isolated signal transmission. The S1 designation indicates specific lead bending suitable for SMD placement. Verify that the 5000 Vrms isolation rating meets the safety standards of your application. Consider the operating temperature range and current transfer ratio specifications to ensure compatibility with the driving circuit and load requirements.
Part Context
This part belongs to the EL817 series of photocouplers from Everlight Electronics. The series includes various configurations such as DIP and SMD packages with different lead forms. The EL817 family is widely recognized for its reliability in providing electrical isolation. This specific variant integrates surface-mount compatible leads and tape-and-reel packaging for efficient manufacturing integration.
Replacement Considerations
Consult the official Everlight datasheet for direct pin-compatible alternatives within the EL817 series. Verify that any substitute maintains the same isolation voltage, output transistor type, and package dimensions. Cross-reference safety approvals such as UL and VDE if required by your application standards.
