Overview
The PS2566L2-1-A is a single-channel transistor output optocoupler manufactured by CEL. It features a GaAs light emitting diode coupled to an NPN silicon Darlington phototransistor in a surface-mount package with long creepage distance leads. Key electrical parameters include a typical current transfer ratio of 2000%, an isolation voltage of 5000 Vrms, and a maximum collector-emitter saturation voltage of 1 V. The device supports a maximum forward current of 80 mA and operates within a temperature range of -55°C to +100°C.
Feature Summary
- High isolation voltage capability for AC input applications
- High current transfer ratio for efficient signal transmission
- Surface mount configuration with extended lead bending for increased creepage distance
Applications
- AC input detection circuits
- Industrial control systems requiring high isolation
- Power supply feedback loops
Procurement Notes
Verify component availability as the part status may be discontinued or restricted in certain regions. Confirm RoHS compliance details through official documentation before integration. Ensure ordering suffixes match specific packaging or approval requirements such as UL or VDE recognition when applicable to the target market regulations.
Selection Notes
Select this component for designs requiring high isolation voltage and high gain in a compact surface-mount form factor. Consider the long creepage distance leads for enhanced safety in high-voltage environments. Evaluate thermal management needs given the power dissipation limits and operating temperature range specified in the datasheet.
Part Context
This part belongs to the NEPOC series of high isolation voltage photocouplers from CEL. It is part of a family including DIP and various surface-mount variants like PS2566L1-1 and PS2566L2-4. The series is designed for robust signal isolation in demanding electronic applications.
Replacement Considerations
Cross-reference with other PS2566L2-1 variants from CEL or compatible manufacturers offering similar isolation voltages and Darlington outputs. Verify pinout compatibility and package dimensions for direct replacement.
