PS2561DL-1Y-A

Overview

The PS2561DL-1Y-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and operates with a forward current of 10 mA. The device provides high isolation voltage of 5000 Vrms, ensuring reliable signal transmission across isolated circuits. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 30 mA, and a power dissipation rating of 150 mW. Switching characteristics are defined by typical rise and fall times of 3 µs and 5 µs, respectively. The component is housed in a 4-pin DIP package.

Feature Summary

• Provides galvanic isolation between input and output circuits using optical transmission
• Features high insulation voltage capability for safe operation in high-voltage environments
• Utilizes NPN phototransistor output for standard digital or analog signal interfacing

Applications

• Programmable logic controller (PLC) I/O modules
• Industrial automation control systems
• Power supply feedback loops

Procurement Notes

Verify the specific suffix 'DL' against official Renesas documentation to confirm pinout configuration and package variant. Ensure compatibility with existing PCB footprints before procurement. Check for end-of-life status or recommended new designations via manufacturer channels. Confirm RoHS compliance requirements match project specifications. Validate supplier authenticity through authorized distribution networks.

Selection Notes

Select this component when high isolation voltage is required alongside moderate switching speeds. The NPN output type suits applications requiring open-collector configurations. Consider thermal management due to 150 mW power dissipation limit. Evaluate CTR ranges if precise gain control is necessary for the application circuit. Compare against similar series parts for package availability and cost efficiency.

Part Context

This part belongs to the PS2561 family of high-isolation voltage photocouplers from Renesas. The family includes variants with different packaging options such as surface mount and through-hole DIP configurations. These components are designed for general-purpose isolation in industrial and commercial equipment. The DL suffix typically denotes a specific lead form or package style within the broader product line.

Replacement Considerations

Consult official cross-reference lists for direct replacements. Verify pinout compatibility and electrical parameter equivalence before substitution. Ensure safety certification approvals remain valid for the replacement component.
