Overview
The EL816(S)(B)(TU) is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with a phototransistor detector, providing electrical isolation between input and output circuits. The device features a minimum collector-emitter breakdown voltage of 80 V and supports a maximum forward current of 50 mA. It offers a high isolation voltage of 5000 Vrms and operates within a temperature range of -55°C to +110°C. The component is RoHS compliant and utilizes a surface-mount SMD package.
Feature Summary
- High isolation voltage capability between input and output channels
- Wide operating temperature range suitable for demanding environments
- Compact surface-mount packaging design
Applications
- Signal isolation in industrial control systems
- Switching power supply feedback loops
- Microcontroller interface circuits requiring galvanic isolation
Procurement Notes
Verify the specific suffix (S)(B)(TU) against official Everlight documentation to confirm pinout configuration and tape-and-reel specifications. Ensure compliance with RoHS directives and check for UL or VDE approvals if required by your application standards. Confirm availability through authorized distributors as lead times may vary.
Selection Notes
Select this component when high isolation voltage and wide temperature operation are required in a compact form factor. Consider the CTR range and collector-emitter saturation voltage for signal integrity. Verify that the surface-mount package aligns with your PCB assembly capabilities and space constraints.
Part Context
This part belongs to the EL816 series of transistor output optocouplers from Everlight. The series is widely used for general-purpose isolation applications. The specific suffix indicates the package type and reel configuration. It serves as a standard solution for isolating low-voltage digital signals from higher voltage analog or power circuits.
Replacement Considerations
Check for direct substitutes such as EL816(S)(X)(TA) or similar variants within the same family. Ensure replacement parts match the isolation voltage, CTR, and package dimensions. Verify that any alternative maintains the same safety certifications and thermal characteristics.
