Procurement Notes
Verify the manufacturer designation, as this component is also listed under Renesas Electronics Corporation due to corporate acquisition history. Confirm the specific suffix matches the required creepage distance and packaging variant. Ensure compliance with RoHS standards if applicable to the target market. Cross-reference the datasheet version to confirm parameter consistency.
Selection Notes
Select this component when high isolation voltage and high-temperature stability are required in a small form factor. Compare the CTR range and switching speeds against system requirements. Consider the SMD package type for PCB layout constraints. Verify that the 80 V output voltage rating meets the load requirements.
Part Context
This part belongs to the PS2561D family of transistor output optocouplers. The 'L2' suffix typically denotes long creepage distance variants. The series is widely used in applications demanding robust isolation performance. Related parts include DIP versions and different isolation voltage ratings within the same product line.
Replacement Considerations
Direct substitutes may include PS2561DL2-1Y-F3-A or PS2561BL2-1Y-A-W. Verify pinout compatibility and electrical specifications before substitution. Check for equivalent isolation ratings and thermal characteristics.
