Procurement Notes
This component is scheduled for obsolescence and will be discontinued by the manufacturer. Verify current availability status through authorized distributors before finalizing designs. Due to the end-of-life status, long-term supply continuity cannot be guaranteed. Engineering teams should assess inventory needs carefully and consider alternative solutions for new production runs to mitigate future sourcing risks.
Selection Notes
Select this component when a built-in reference voltage simplifies error amplifier circuitry. The integrated 2.495 V reference reduces external component count compared to standard optocouplers. Ensure the 70 V collector-emitter voltage rating meets system requirements. The SMD-DIP-8 package facilitates automated assembly while maintaining high isolation performance for safety-critical applications.
Part Context
The FOD2743BSV belongs to the FOD2743B series of optically isolated amplifiers from onsemi. This series is designed for applications requiring precise signal transmission across isolation barriers. The device combines optical coupling with internal reference generation, distinguishing it from basic digital optocouplers. It serves as a specialized solution for analog feedback paths in power electronics.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Given the obsolescence status, consult onsemi technical support for recommended alternatives or transition plans.
