PS2561DL-1Y-F3-Q-A

Overview

The PS2561DL-1Y-F3-Q-A is a single-channel transistor output optocoupler manufactured by CEL. It features a surface-mount package with long creepage distance, designed for high-temperature operation up to 110°C. The device provides an isolation voltage of 5000 Vrms and utilizes an NPN phototransistor output. Key electrical parameters include a maximum collector-emitter voltage of 80V, a collector current of 50mA, and a forward voltage of approximately 1.2V at 10mA input. Rise and fall times are typically 3µs and 5µs respectively.

Feature Summary

• High isolation voltage capability of 5000 Vrms
• Extended operating temperature range up to 110°C
• Long creepage distance design for enhanced safety
• Single channel NPN phototransistor output

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback circuits
• Signal transmission across isolated barriers

Procurement Notes

Verify the specific suffix Q-A against official CEL documentation to confirm package type and tape/reel specifications. Ensure the procurement source provides valid RoHS compliance certificates as indicated in related product descriptions. Cross-reference the manufacturer part number with Renesas datasheets if sourcing from authorized distributors, as Renesas holds rights to the PS2561 series. Confirm lead times and packaging quantities directly with the supplier prior to order placement.

Selection Notes

Select this component when high isolation voltage and long-term reliability at elevated temperatures are required. The long creepage distance makes it suitable for applications demanding strict safety standards. Compare the 5000 Vrms rating against system insulation requirements. Consider the 110°C operating limit for thermal management in enclosed environments. Verify that the NPN output configuration matches the downstream circuit logic requirements.

Part Context

This component belongs to the PS2561 family of transistor output optocouplers. The DL variant specifically denotes a surface-mount package with extended creepage distances compared to standard DIP versions. Related parts include PS2561DL-1Y-F3-L-A and PS2561DL-1Y-F3-A, which share similar electrical characteristics but may differ in packaging or reel specifications. The series is widely used in industrial and consumer electronics for signal isolation.

Replacement Considerations

Direct substitutes include PS2561DL-1Y-F3-L-A and PS2561DL-1Y-F3-A from CEL. Renesas equivalents such as PS2561DL2-1Y-F3-A/ H or /Q may be compatible but require verification of pinout and mechanical dimensions. Ensure replacement parts maintain the same 5000 Vrms isolation rating and 110°C temperature class.
