PS2561L2-1-V-F3-L-A

Overview

The PS2561L2-1-V-F3-L-A is a single-channel transistor output optocoupler manufactured by CEL. It features a 4-pin SMD gull-wing package designed for surface mount applications with extended creepage distance. The device provides an isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a minimum current transfer ratio of 200% at 5mA forward current, a maximum collector-emitter voltage of 80V, and a maximum collector current of 50mA. The unit operates within a temperature range of -55°C to +100°C and dissipates up to 150mW of power.

Feature Summary

• High isolation voltage capability of 5000 Vrms for robust circuit separation
• Gull-wing lead bending design specifically engineered for long creepage distance in surface mount configurations
• Single channel configuration utilizing NPN phototransistor output for signal transmission

Applications

• Industrial control systems requiring galvanic isolation
• Measurement and testing equipment interfaces
• Power supply feedback loops

Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to ensure compatibility with required insulation standards and packaging formats. Confirm that the gull-wing package variant matches the PCB footprint requirements. Check for end-of-life or obsolescence status prior to finalizing procurement decisions to avoid supply chain disruptions during production phases.

Selection Notes

Select this component when high isolation voltage and extended creepage distance are critical for safety compliance in surface mount designs. Ensure the forward current and collector current ratings align with the target circuit load requirements. Consider the operating temperature range limits for environments subject to extreme thermal conditions during system integration planning.

Part Context

This part belongs to the PS2561L2-1 series of transistor output optocouplers from CEL. The series is characterized by its use of gull-wing leads to enhance insulation performance compared to standard flat packages. It serves as a specialized solution for applications demanding higher dielectric strength than standard DIP optocouplers can provide in compact surface mount form factors.

Replacement Considerations

Cross-reference with PS2561L2-1-E3-A or PS2561L2-1-E4-A for similar specifications. Verify pinout compatibility and package dimensions before substitution. Ensure replacement parts meet the same 5000 Vrms isolation requirement.
