PS2561AL-1-F3-W-A

Overview

The PS2561AL-1-F3-W-A is a single-channel transistor output optocoupler manufactured by CEL. It features an NPN phototransistor output with a high isolation voltage of 5000 Vrms. The device supports a maximum forward current of 30 mA and a collector current of 50 mA, with a maximum collector-emitter voltage of 70 V. The current transfer ratio ranges from 130% to 260% at 5 mA input. It operates within a temperature range of -55°C to +100°C and utilizes a 4-SMD gull-wing package.

Feature Summary

• High insulation voltage capability for safe signal transmission
• Single channel configuration for compact circuit design
• Surface mount package suitable for automated assembly

Applications

• Industrial control systems requiring electrical isolation
• Power supply feedback circuits
• Signal isolation in microprocessor interfaces

Procurement Notes

Verify the specific suffix codes against official datasheets to ensure correct packaging and lead form. Confirm RoHS compliance status as required by project specifications. Check for obsolescence notices or lifecycle status before finalizing procurement plans to avoid supply chain disruptions.

Selection Notes

Select this component when high isolation voltage and moderate speed are required. Ensure the forward current requirements do not exceed 30 mA. Verify that the 70 V collector-emitter voltage meets the load requirements. Consider the operating temperature range limits for harsh environments.

Part Context

This part belongs to the PS2561 series of transistor output optocouplers. It shares functional similarities with other variants in the family but differs in package type and specific electrical characteristics. The series is designed for general-purpose isolation applications in electronic circuits.

Replacement Considerations

Cross-reference with PS2561A-1 or PS2561L2-1-F3-A for similar performance. Verify pinout compatibility and electrical parameters before substitution. Consult manufacturer documentation for direct replacements.
