Overview
The EL817(S1)(TA)-G is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output and operates with a DC input. The device provides high isolation voltage of 5000 Vrms between input and output circuits. It is designed for surface mount applications in a compact small outline package. The component supports a wide operating temperature range from -55°C to +110°C and complies with RoHS standards.
Feature Summary
- High isolation voltage capability between input and output terminals
- Compact surface mount small outline package design
- Wide operating temperature range suitable for industrial environments
- RoHS compliant construction without lead content
Applications
- Industrial control systems requiring signal isolation
- Computer peripheral interface circuits
- Power supply feedback loop isolation
- Signal transmission across isolated ground planes
Procurement Notes
Verify the specific suffix TA indicates tape and reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the component matches the required surface mount footprint dimensions for PCB layout compatibility. Check current availability status as distribution channels may vary.
Selection Notes
Select this component when surface mount assembly is required for single-channel isolation. Verify that the NPN phototransistor output type aligns with the receiving circuit requirements. Ensure the 5000 Vrms isolation rating meets the safety standards of the target application. Confirm thermal management capabilities within the specified temperature range.
Part Context
This part belongs to the EL817 series of transistor output optocouplers from Everlight. The series offers various packaging options including DIP and SMD configurations. The EL817 family is widely used for general purpose isolation in electronic circuits. Variations in suffixes typically denote packaging or compliance differences rather than functional changes.
Replacement Considerations
Cross-reference with other EL817 variants such as EL817(S1)(D)(TA)-G for alternative packaging options. Verify pinout compatibility before substituting with generic transistor output optocouplers. Ensure replacement parts maintain equivalent isolation voltage and current transfer ratio specifications.
