Overview
The EL816(S)(Y)(TU) is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with an NPN phototransistor detector, providing electrical isolation between input and output circuits. The device features a high isolation voltage of 5000 Vrms and supports a maximum collector-emitter breakdown voltage of 80 V. It operates within a temperature range of -55°C to +110°C and is available in a surface-mount package configuration compliant with RoHS standards.
Feature Summary
- High isolation voltage capability between input and output channels
- Compact surface-mount package design for space-constrained applications
- RoHS compliant construction without lead content
- Wide operating temperature range suitable for industrial environments
Applications
- Signal transmission between circuits of different potentials
- Programmable logic controller interfaces
- Telecommunication equipment signal isolation
- System appliances and measuring instruments
Procurement Notes
Verify the specific suffix (Y)(TU) against official Everlight documentation to confirm exact packaging type and tape-and-reel specifications. Ensure compliance requirements match project needs, as the component is RoHS compliant. Confirm availability status directly with authorized distributors, as supply conditions may vary. Cross-reference datasheet revisions to ensure parameter consistency before integration into final designs.
Selection Notes
Select this component when high isolation voltage and compact surface-mount form factors are required. The NPN phototransistor output is suitable for digital signal switching applications. Verify that the current transfer ratio meets system gain requirements at the intended operating current. Ensure thermal management strategies account for the specified operating temperature limits during continuous operation.
Part Context
This component belongs to the EL816 series of phototransistor optocouplers from Everlight Electronics. The series offers various package options including DIP and SMD configurations. The EL816 family is widely used for general-purpose isolation tasks in industrial and consumer electronics due to its reliability and standardized pinout compatibility with industry-standard optocoupler footprints.
Replacement Considerations
Direct substitutes include other EL816 variants with compatible pinouts such as EL816(S)(X)(TA). Verify isolation voltage and CTR specifications match application requirements when selecting alternatives. Ensure replacement components maintain the same package dimensions and mounting characteristics for board compatibility.
