PS2561AL-1-W-A

Overview

The PS2561AL-1-W-A is a single-channel transistor output optocoupler manufactured by CEL. It integrates a Gallium Arsenide (GaAs) infrared emitting diode with an NPN silicon phototransistor in a surface-mount plastic package. The device provides high isolation voltage of 5000 Vrms and features a nominal current transfer ratio ranging from 130% to 260% at a forward current of 5 mA. It operates within a temperature range of -55 °C to 100 °C, supports a maximum forward current of 30 mA, and offers a collector-emitter breakdown voltage of 70 V.

Feature Summary

High isolation voltage capability for safe signal transmission between isolated circuits
Integrated GaAs LED and NPN phototransistor for efficient optical coupling
Surface-mount gull-wing package design for automated assembly

Applications

Industrial control systems requiring galvanic isolation
Power supply feedback loops
Signal isolation in microprocessor interfaces

Procurement Notes

Verify the specific suffix 'W-A' against official manufacturer documentation to confirm lead form and tape/reel specifications. Ensure compliance with RoHS directives if required. Confirm that the supplier source aligns with authorized distribution channels to guarantee component authenticity and traceability.

Selection Notes

Select this component when a surface-mount solution with high isolation voltage is required. Compare the 130%-260% CTR range against circuit requirements. Verify that the 4-pin SMD footprint matches the PCB layout constraints. Consider thermal management capabilities within the specified operating temperature range.

Part Context

This part belongs to the PS2561A series of photocouplers, which are designed for cost-effective isolation applications. The series includes various package options such as DIP and surface-mount variants. The AL designation typically indicates a lead-bending type suitable for surface mounting, while the W-A suffix denotes specific packaging or reel configuration details defined by the manufacturer.

Replacement Considerations

Direct replacements include PS2561AL-1-E3-A-L and PS2561BL2-1-E3-A. Verify pin compatibility and electrical parameters such as CTR and isolation voltage before substitution.
