Overview
The EL815-V is a single-channel photodarlington output optocoupler manufactured by Everlight Electronics Co Ltd. It provides electrical isolation between input and output circuits with an insulation voltage of 5000 Vrms. The device features a high current transfer ratio, specified as a minimum of 600% at an input forward current of 1mA and collector-emitter voltage of 2V. Packaged in a standard 4-pin DIP configuration, it is designed for applications requiring robust signal transmission across isolated boundaries.
Feature Summary
- High current transfer ratio capability for efficient signal coupling
- High isolation voltage rating between input and output terminals
- Photodarlington output structure for enhanced sensitivity
Applications
- Telephone sets
- Telephone exchangers
Procurement Notes
Verify the specific suffix variant (e.g., M, S1, TD) against the required lead spacing or packaging format, as these designators affect physical dimensions rather than electrical function. Confirm component status, as availability may vary by region. Ensure compliance with relevant RoHS directives if applicable to the specific manufacturing batch.
Selection Notes
Select this component when high gain is required from a single-stage optical interface. The photodarlington output offers superior sensitivity compared to standard phototransistor variants. Verify that the 5000 Vrms isolation rating meets the safety requirements of the target application environment.
Part Context
This part belongs to the EL815 series of transistor output optocouplers. The series includes various package options such as wide-lead DIP and surface mount devices. The EL815-V designation specifically refers to the base model configuration within this family, distinguished by its Darlington output architecture.
Replacement Considerations
Compatible substitutes include the EL815(S1)(TD)-V and EL815(S1)(TU)-V. These variants share the same core electrical characteristics but differ in lead spacing or packaging style. Verify pinout compatibility before substitution.
