Overview
The PS2565L-1-K-A is a single-channel transistor output optocoupler manufactured by CEL. It features an NPN silicon phototransistor coupled with a GaAs infrared LED, providing electrical isolation with a rated insulation voltage of 5000 Vrms. The device utilizes a surface-mount SMD-4 package with gull-wing leads designed for long creepage distance applications. Key electrical specifications include a maximum collector-emitter voltage of 80 V and a maximum collector current of 50 mA. The unit operates within a temperature range of -55°C to +100°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Utilizes surface-mount technology with gull-wing leads for extended creepage distance
- Integrates a GaAs LED with an NPN silicon phototransistor for signal transmission
Applications
- Industrial control systems requiring galvanic isolation
- Signal interfacing in microprocessor-based circuits
- Power supply feedback loops
Procurement Notes
Verify the specific suffix 'K-A' against official datasheets to confirm lead configuration and creepage distance requirements. Confirm RoHS compliance status as manufacturing standards may vary by production batch. Ensure the selected variant matches the required surface-mount footprint and thermal characteristics for the target application environment.
Selection Notes
Select this component when a surface-mount solution with enhanced creepage distance is required for high-voltage isolation. Compare the 5000 Vrms insulation rating against system safety standards. Evaluate the 80 V collector-emitter voltage limit to ensure compatibility with downstream logic or switching levels. Consider the operating temperature range for environmental suitability.
Part Context
This part belongs to the NEPOC family of transistor output optocouplers from CEL. The series typically includes variants with different channel counts and package types, such as DIP and SOP configurations. The 'L' designation often indicates specific lead bending or creepage enhancements compared to standard counterparts within the same product line.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical parameters before considering alternative manufacturers.
