PS2561DL2-1Y-Q-A

Overview

The PS2561DL2-1Y-Q-A is a single-channel transistor output optocoupler manufactured by CEL. It features an NPN phototransistor output and provides 5000 Vrms isolation voltage. The device utilizes a 4-SMD surface-mount package with long creepage distance, designed for high-temperature operation up to 110°C. It complies with BSI and VDE safety standards and is RoHS compliant.

Feature Summary

• High insulation voltage of 5000 Vrms for reliable signal isolation
• Surface-mount design with extended creepage distance for enhanced safety
• Capable of operating at elevated temperatures up to 110°C
• Complies with international safety certifications including BSI and VDE

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback circuits
• Signal transmission in noisy electrical environments

Procurement Notes

Verify the specific suffix Q-A against official CEL documentation to confirm exact packaging and compliance details. Ensure the component matches the required 4-SMD form factor and temperature rating for your application. Cross-reference the manufacturer part number with Renesas Electronics records if sourcing through alternative channels, as brand ownership may have changed.

Selection Notes

Select this component when high isolation voltage and long creepage are critical for safety compliance. The SMD package suits automated assembly processes. Verify that the NPN output configuration aligns with the receiving circuit requirements. Confirm that the 110°C maximum operating temperature meets the thermal constraints of the final enclosure.

Part Context

This part belongs to the PS2561 series of transistor output optocouplers. The DL2 designation typically indicates a specific lead form or package variation within the family. CEL (California Eastern Laboratories) is the listed manufacturer, though Renesas Electronics also appears in related databases, indicating potential corporate acquisition or distribution overlap.

Replacement Considerations

Direct substitutes include PS2561DL2-1Y-V-F3-A and PS2561DL2-1Y-V-H-A from the same manufacturer line. These variants share similar isolation and output characteristics but may differ in specific packaging or certification suffixes. Verify pinout compatibility before substitution.
