Procurement Notes
Verify the manufacturer designation as CEL when sourcing this specific part number. Confirm the package style matches the required surface mount footprint. Ensure the operating temperature range meets the application's thermal requirements. Check for RoHS compliance status if environmental regulations apply. Validate the datasheet version to confirm electrical parameters such as CTR and isolation voltage.
Selection Notes
Select this component for applications requiring a single channel of isolation with transistor output. Consider the 5000 Vrms isolation rating for safety-critical designs. Evaluate the 130% to 260% CTR range against the load requirements. Ensure the SMD package fits the PCB layout constraints. Verify compatibility with the driving circuit's forward current limits.
Part Context
This part belongs to the PS2561 series of transistor output optocouplers. The series includes various package options and lead configurations. The DL1 suffix typically indicates a specific surface mount variant. Other variants may differ in insulation clearance or packaging format. The series is commonly used in industrial and consumer electronics for signal isolation.
Replacement Considerations
Direct replacements include PS2561DL1-1-V-A and PS2561DL2-1Y-F3-A. Verify pinout compatibility and electrical parameters before substitution. Check if alternative packages meet the mechanical constraints. Ensure the replacement maintains the required isolation voltage and temperature rating.
