Overview
The EL817(S)(A)(TB)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It integrates an infrared emitting diode and an NPN phototransistor detector within a compact surface-mount package. The device provides high isolation voltage of 5000 Vrms between input and output circuits, ensuring reliable signal transmission in electrically noisy environments. It operates within a temperature range of -55°C to +110°C and complies with RoHS standards.
Feature Summary
- High isolation voltage capability for safe circuit separation
- Compact surface-mount design suitable for automated assembly
- Wide operating temperature range for diverse environmental conditions
Applications
- Signal isolation in industrial control systems
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix configuration against official Everlight documentation to ensure correct pinout and electrical characteristics. Confirm compliance requirements such as UL or VDE recognition if applicable to your design. Cross-reference datasheet revisions to avoid discrepancies in mechanical dimensions or performance parameters during procurement.
Selection Notes
Select this component when surface-mount technology is required for space-constrained designs. Ensure the application voltage does not exceed the collector-emitter breakdown voltage. Consider the current transfer ratio specifications for logic level compatibility. Verify thermal management needs given the operating temperature limits.
Part Context
This part belongs to the EL817 series, a widely used family of photocouplers known for their reliability and cost-effectiveness. The 'S' indicates a surface-mount variant, while '(A)' typically denotes a specific binning or parameter grouping defined by the manufacturer. The '(TB)' suffix often refers to tape-and-reel packaging for automated placement.
Replacement Considerations
Direct substitutes may include other EL817 surface-mount variants from Everlight or equivalent parts from manufacturers like Sharp or Toshiba, provided pinouts and isolation ratings match. Always verify electrical parameters and physical dimensions before substitution.
