Overview
The EL816(M)(Y) is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode optically coupled to an NPN phototransistor detector. The device provides high isolation voltage of 5000 Vrms between input and output circuits. It features a current transfer ratio ranging from 50% to 600% 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 is housed in a 4-pin DIP package.
Feature Summary
- Integrates an infrared emitting diode with an NPN phototransistor for signal transmission
- Provides high electrical isolation between input and output circuits
- Operates reliably across a wide industrial temperature range
- Compliant with lead-free and RoHS environmental standards
Applications
- Signal isolation in DC-DC converter modules
- Low-power application circuit interfacing
- Digital signal transmission between isolated grounds
Procurement Notes
Verify the specific suffix configuration against the manufacturer datasheet, as variations exist within the EL816 series regarding packaging and approval ratings. Confirm availability status as distribution channels may list discontinued or limited stock items. Ensure the selected variant matches the required isolation voltage and package type for the target design.
Selection Notes
Select this component when a single-channel transistor output isolator is required with high voltage isolation capabilities. Consider the CTR range and operating temperature limits relative to the system environment. Verify that the 4-pin DIP package fits the PCB layout constraints. Check for specific safety approvals if the application requires UL or VDE certification.
Part Context
This part belongs to the EL816 series of optocouplers, which are widely used for general-purpose signal isolation. The series typically includes various package options such as DIP and SMD, along with different lead spacing configurations. These devices are designed to replace relay-based isolation in compact electronic designs.
Replacement Considerations
Direct replacements include other EL816 variants with compatible pinouts and electrical characteristics. Verify that substitute parts maintain the same isolation voltage rating and package dimensions. Cross-reference specific suffix codes to ensure matching safety approvals and compliance certifications.
