Overview
The PS2561AL2-1-E4-A is a single-channel transistor output optocoupler manufactured by CEL. It features a 4-SMD gull-wing package designed for surface mount applications. The device provides high isolation voltage of 5000Vrms between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 70V, a maximum DC forward current of 30mA, and a typical forward voltage of 1.2V. The collector-emitter saturation voltage is specified at a maximum of 300mV. Current transfer ratio ranges from 50% to 400% at 5mA input. Operating temperature spans from -55°C to 100°C.
Feature Summary
- High isolation voltage capability of 5000Vrms for robust circuit separation
- Wide lead bending L2 type gull-wing package optimized for surface mount technology
- Single channel configuration with NPN phototransistor output
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal transmission across isolated boundaries
Procurement Notes
Verify component status as the part may be discontinued or not recommended for new designs depending on the specific revision. Confirm package type matches the 4-SMD gull-wing specification. Ensure compatibility with existing PCB footprints. Check for alternative sourcing if original manufacturing lines are closed. Validate insulation ratings against application safety standards.
Selection Notes
Select this component when surface mount assembly is required with high isolation needs. The gull-wing package facilitates automated placement. Consider the 70V collector voltage limit for load switching. Verify thermal management requirements within the -55°C to 100°C operating range. Compare current transfer ratio specifications against drive circuit capabilities.
Part Context
This part belongs to the PS2561 series of transistor output optocouplers. The AL2 suffix indicates the wide lead bending L2 gull-wing package variant. The E4 suffix typically denotes lead-free composition and specific ordering configurations. The series is designed for general-purpose isolation in compact surface mount layouts.
Replacement Considerations
PS2561AL2-1-E3-A is listed as a potential substitute with similar specifications. Verify pinout compatibility and package dimensions before substitution. Confirm that electrical parameters meet original design requirements.
