Overview
The CEL PS2561-1 is a single-channel transistor output optocoupler featuring an AlGaAs LED and an NPN silicon phototransistor. It provides high isolation voltage of 5000 Vrms with a collector-emitter breakdown voltage of 70 V. The device operates within a temperature range of -55 °C to 100 °C, supports a maximum forward current of 30 mA, and maintains a low dark current of 100 nA.
Feature Summary
- Integrates an AlGaAs light emitting diode with an NPN silicon phototransistor for signal isolation
- Provides high electrical isolation capability between input and output circuits
- Constructed in a plastic dual in-line package (DIP) configuration
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal transmission across isolated barriers
Procurement Notes
Verify the specific manufacturer designation as the model number appears associated with multiple vendors including NEC/Renesas and CEL. Confirm that the component meets required safety certifications such as UL or CSA if applicable to your design. Ensure the package type matches the PCB footprint requirements before ordering.
Selection Notes
Select this component when a standard single-channel transistor output isolator is needed. Consider the 70 V collector-emitter breakdown voltage and 5000 Vrms isolation rating for circuit compatibility. Verify the operating temperature range fits the environmental conditions of the application.
Part Context
This component belongs to the PS2561 series of high isolation voltage photocouplers. The series typically includes variants with different lead forms and packaging options. The PS2561-1 specifically denotes the DIP package version of this single-channel transistor output isolator family.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other manufacturers offering equivalent single-channel transistor output optocouplers with similar isolation ratings and pin configurations.
