Overview
The EL816(S1)(D)(TU) is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with an NPN phototransistor detector to provide electrical isolation between input and output circuits. The device features a high isolation voltage of 5000 Vrms and supports surface mount installation in a compact SMD package. It operates within a temperature range of -55°C to +110°C, with a maximum collector-emitter breakdown voltage of 80V and a continuous output current of 50mA.
Feature Summary
- High isolation voltage capability between input and output channels
- Compact surface mount design for space-constrained applications
- Wide operating temperature range suitable for industrial environments
Applications
- Digital logic signal transmission and conversion
- Power supply control and switching circuits
- Electrical insulation isolation between circuit stages
- Impedance transformation between system components
Procurement Notes
Verify the specific suffix codes against official Everlight documentation to confirm pinout configuration and packaging type. Ensure compliance requirements match project specifications. Confirm availability status as distribution channels may vary. Cross-reference datasheet revisions to ensure parameter consistency before integration into final designs.
Selection Notes
Select this component when high voltage isolation is required in a small form factor. The NPN phototransistor output is suitable for digital switching applications. Consider the CTR range and operating temperature limits relative to the target environment. Verify that the surface mount package aligns with PCB assembly capabilities and thermal management requirements.
Part Context
This part belongs to the EL816 series of optocouplers from Everlight Electronics. The series typically includes various packaging options such as DIP and SMD configurations. These devices are designed for general-purpose isolation tasks where reliable signal transfer across isolated boundaries is necessary without direct electrical connection.
Replacement Considerations
Check for compatible substitutes within the same family or equivalent performance levels from other manufacturers. Ensure replacement parts maintain identical isolation voltage ratings and pin compatibility if board space is constrained.
