Overview
The PS2566L-1-A is a single-channel transistor output optocoupler from the CEL NEPOC series, designed for high isolation voltage AC input applications. It integrates a GaAs light emitting diode with an NPN silicon Darlington connected phototransistor in a lead bending type package suitable for surface mount. Key electrical parameters include a maximum collector-emitter voltage of 40 V, a maximum collector current of 200 mA, and a forward current rating of 80 mA. The device offers a typical current transfer ratio (CTR) of 2000% and supports an operating temperature range from -55°C to +100°C.
Feature Summary
- High isolation voltage capability rated at 5000 Vrms
- AC input response compatibility
- Surface mount lead bending configuration for long creepage distance
- High current transfer ratio performance
Applications
- Industrial control systems requiring signal isolation
- Automation equipment interfaces
- Power supply feedback circuits
Procurement Notes
Verify component authenticity through authorized CEL distributors or certified suppliers. Confirm RoHS compliance status via official documentation. Check for obsolescence notices as this specific suffix may indicate discontinued status. Ensure storage conditions maintain integrity prior to assembly. Validate pinout alignment with PCB footprint specifications before procurement finalization.
Selection Notes
Select this component when high isolation voltage and AC input compatibility are required. The surface mount package facilitates automated assembly processes. Consider the high CTR for driving loads with minimal input current. Verify thermal management requirements given the power dissipation limits. Ensure the 40V collector-emitter voltage meets circuit switching demands.
Part Context
This part belongs to the PS2566 series of multi photocouplers manufactured by CEL. The series includes various channel configurations and package types, such as DIP and SMD variants. The PS2566L-1-A specifically denotes a single-channel unit with lead bending features for surface mounting, distinguishing it from standard DIP versions within the same functional family.
Replacement Considerations
Direct substitutes include other PS2566L-1 variants with compatible suffixes like E3 or E4 if available. Cross-reference with similar high-isolation Darlington optocouplers from other manufacturers only after verifying pinout and electrical parameter equivalence. Ensure replacement parts meet the same safety approval standards.
