Overview
The PS2561AL2-1-V-F3-W-A is a single-channel transistor output optocoupler manufactured by CEL. It features an NPN phototransistor output and provides high isolation voltage of 5000 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 80 V, maximum collector current of 50 mA, and forward voltage of 1.4 V at 80 mA forward current. The device operates within a temperature range of -55°C to +100°C with a power dissipation of 150 mW.
Feature Summary
- High isolation voltage capability for safe signal transmission between isolated circuits
- Wide lead bending design optimized for surface mount applications
- Single channel configuration with NPN phototransistor output
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal isolation in microprocessor interfaces
Procurement Notes
Verify the specific suffix 'V' indicates the wide lead bending package variant as documented in official datasheets. Confirm RoHS compliance status through the manufacturer's current documentation. Ensure the ordering number matches the exact pinout and creepage requirements for your PCB layout. Cross-reference the manufacturer part number with distributor listings to confirm availability and authenticity.
Selection Notes
Select this component when high isolation voltage is required in a surface mount form factor. The wide lead design facilitates automated assembly while maintaining creepage distances. Consider the NPN output type and current transfer ratio specifications for driving subsequent logic stages. Verify thermal management capabilities given the 150 mW power dissipation rating.
Part Context
This part belongs to the PS2561A series of transistor output optocouplers from CEL. The series is designed for general-purpose isolation applications. The AL2 designation typically refers to specific packaging or performance variants within the family. These devices are commonly used where compact size and reliable isolation are critical.
Replacement Considerations
Check for direct substitutes such as PS2561AL2-1-E3 or PS2561AL2-1-F3 which share similar electrical characteristics but may differ in packaging or taping specifications. Verify pin compatibility and isolation voltage ratings before substitution.
