Overview
The PS2561-1-V-D-A is a single-channel transistor output optocoupler manufactured by CEL. It integrates a GaAs infrared LED and an NPN silicon phototransistor within a plastic DIP-4 package. Key electrical parameters include a maximum forward current of 0.03 A, a collector-emitter breakdown voltage of 80 V, and a nominal current transfer ratio of 300% at 5 mA. The device provides high isolation with a maximum insulation voltage of 5000 V. Operating temperatures range from -55 °C to 100 °C, with typical rise and fall times of 3 µs and 5 µs respectively.
Feature Summary
- Integrates a GaAs light emitting diode and an NPN silicon phototransistor for optical signal transmission
- Provides high isolation voltage capability suitable for noise-immune circuit applications
- Features a standard plastic dual in-line package designed for through-hole mounting
Applications
- Signal isolation in industrial control systems
- Interface circuits between microprocessors and power devices
- Switching applications requiring galvanic isolation
Procurement Notes
Verify component authenticity through authorized distributors or certified suppliers. Confirm the specific suffix matches the required package and lead-free specifications. Check manufacturer documentation for current availability status as this part may be discontinued. Ensure compliance with relevant safety standards such as UL recognition before integration into final products.
Selection Notes
Select this component when a single-channel transistor output is required with high isolation voltage. Consider the 300% current transfer ratio for efficient signal coupling. Verify that the DIP-4 package fits the PCB layout constraints. Compare operating temperature ranges against environmental requirements. Evaluate the trade-off between speed and isolation performance for the specific application.
Part Context
This component belongs to the PS2561 series of photocouplers produced by California Eastern Laboratories (CEL). The series includes various packages and configurations, with the PS2561-1-V-D-A representing a specific DIP-4 variant. It is part of a broader family of optically coupled isolators designed for cost-effective isolation solutions.
Replacement Considerations
Parametric equivalents are available. The PS2501-1-A-D is listed as a substitute option. Verify pinout compatibility and electrical specifications before replacement.
