Procurement Notes
Verify component status carefully as the PS2711-1-L-A is listed as discontinued by major distributors such as DigiKey and Mouser. Confirm availability through alternative channels or authorized agents if sourcing is required. Check for valid RoHS compliance documentation and ensure the specific suffix matches the required pin configuration and packaging type before finalizing procurement decisions.
Selection Notes
Select this component for applications requiring high isolation voltage in a compact form factor. Ensure the input forward current does not exceed 50mA and the output voltage remains within the 40V limit. Consider the thermal constraints given the 150mW power dissipation rating and verify that the operating temperature range suits the environmental conditions of the target system.
Part Context
This part belongs to the PS2711 series of transistor output optocouplers. The series is characterized by small size and high isolation capabilities, suitable for general-purpose signal isolation. The manufacturer history includes transitions between California Eastern Laboratories (CEL) and Renesas Electronics, reflecting industry consolidation trends in semiconductor manufacturing.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Users should consult official manufacturer documentation for equivalent recommendations or cross-reference compatible devices based on electrical specifications.
