- Compact dual-in-line style surface mount package design
- NPN phototransistor output configuration
Applications
- Industrial control systems requiring signal isolation
- Consumer electronics with safety isolation requirements
- Power supply feedback loops
Procurement Notes
Verify the specific suffix (S1)(A)(TA)-G against official Everlight documentation to confirm the exact lead bend and tape/reel type. Ensure compatibility with automated surface mount assembly processes. Confirm RoHS compliance status through current datasheets as manufacturing standards may evolve. Check for any obsolescence notices or lifecycle changes directly from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when surface mount technology is required for space-constrained designs. The S1 variant offers specific lead bending suitable for certain PCB layouts. Verify that the 5000 Vrms isolation rating meets the safety standards of the target application. Consider the NPN output characteristics for logic interface compatibility. Ensure the operating temperature range aligns with the environmental conditions of the end-use product.
Part Context
This part belongs to the EL817 series of photocouplers from Everlight Electronics. The series includes various packaging options such as DIP and SMD configurations. The EL817 family is widely recognized for its reliability in isolation applications. The specific model integrates standard optocoupler functionality within a modern surface-mount form factor.
Replacement Considerations
Direct substitutes include other EL817 variants with compatible pinouts and electrical ratings. Verify equivalent isolation voltage and current transfer ratio specifications. Ensure the replacement component matches the required package dimensions and mounting style.
