Procurement Notes
Verify component authenticity through official manufacturer channels or authorized distributors. Confirm the specific suffix matches the required package and performance specifications. Check for end-of-life status or obsolescence notices before finalizing procurement plans to ensure long-term supply stability.
Selection Notes
Select this component when high isolation voltage and high current gain are required in a compact form factor. Ensure the circuit design accommodates the specified power dissipation limits and operating temperature range. Verify that the input current requirements align with the driving source capabilities.
Part Context
This part belongs to the PS2532L series of multi-channel photocouplers manufactured by CEL. These devices integrate a GaAs light emitting diode with NPN silicon Darlington-connected phototransistors. The series is designed for applications requiring high reliability and electrical isolation in industrial and commercial environments.
Replacement Considerations
Cross-reference with PS2532L-2-A or similar variants from the same family for pin-compatible alternatives. Verify functional equivalence regarding isolation voltage and current transfer ratio before substitution.
