Overview
The EL816(S1)(D)(TA) is a single-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features an infrared emitting diode optically coupled to an NPN phototransistor detector in a compact 4-SMD surface-mount package. The device provides high isolation voltage of 5000 Vrms between input and output circuits with a creepage distance exceeding 7.62 mm. Key electrical parameters include a collector-emitter breakdown voltage of 80 V minimum, a maximum forward current of 60 mA, and a maximum collector current of 50 mA. The unit operates within a temperature range of -55°C to +110°C and complies with RoHS standards.
Feature Summary
- High isolation voltage capability between input and output circuits
- Compact small outline surface-mount package design
- Wide operating temperature range for industrial environments
Applications
- Signal isolation in digital communication systems
- Switching power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix (D)(TA) against official Everlight documentation to confirm pin configuration and tape-and-reel packaging details. Ensure compliance requirements match project specifications. Cross-reference datasheet revisions to confirm parameter consistency. Confirm availability status through authorized distributors as supply conditions may vary.
Selection Notes
Select this component when surface-mount assembly is required for signal isolation applications. Consider the 5000 Vrms isolation rating for safety-critical interfaces. Evaluate the 4-SMD footprint compatibility with PCB layout constraints. Verify thermal management needs given the wide operating temperature range and surface-mount construction.
Part Context
This part belongs to the EL816 series of transistor output optocouplers from Everlight Electronics. The series includes various package options including DIP and SMD configurations. The EL816 family is designed for general-purpose isolation applications requiring reliable signal transmission across isolated boundaries while maintaining electrical safety standards.
Replacement Considerations
Direct substitutes include other EL816 variants with compatible pinouts such as EL816(S1)(X)(TA). Verify mechanical dimensions and electrical characteristics before substitution. Alternative brands offer similar transistor output optocouplers but require validation of isolation ratings and package compatibility.
