EL817(S)(A)(TD)

Overview

The EL817(S)(A)(TD) is a single-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features an NPN phototransistor output and operates within a temperature range of -55°C to 110°C. The device provides 5000 Vrms isolation voltage between input and output. Key electrical parameters include a maximum collector-emitter voltage of 35V, a maximum forward current of 60mA, and a typical rise/fall time of 4µs/3µs. The component is RoHS compliant and housed in a 4-SMD (鸥翼) surface-mount package.

Feature Summary

Provides high-voltage electrical isolation between input and output circuits
Utilizes an NPN phototransistor for signal transmission
Designed for surface-mount assembly with鸥翼 lead configuration

Applications

Signal isolation in industrial control systems
Power supply feedback loops
Communication interface isolation

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm pinout compatibility and packaging type. Ensure the procurement source provides valid RoHS compliance documentation. Cross-reference the part number with Everlight Electronics Co Ltd official records to avoid counterfeit components. Confirm that the SMD鸥翼 package matches the intended PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when surface-mount technology is required for compact designs. The 5000 Vrms isolation rating suits applications demanding robust galvanic separation. Verify that the 35V collector-emitter voltage meets the load requirements. Consider the operating temperature range of -55°C to 110°C for environmental suitability. Ensure the NPN output configuration aligns with the downstream circuit logic.

Part Context

This component belongs to the EL817 series of transistor output optocouplers produced by Everlight Electronics Co Ltd. The series includes various package options such as DIP and SMD variants. The EL817(S)(A)(TD) specifically denotes the surface-mount鸥翼 package variant. This family is widely used for general-purpose isolation tasks requiring reliable signal transfer across isolated boundaries.
