Overview
The PS2561A-1-H-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and operates in a DIP-4 Gull Wing surface-mount package. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 30 mA, and a forward voltage of 1.2 V at a forward current of 10 mA. The device provides high isolation with a rating of 5000 Vrms. Performance metrics specify a minimum current transfer ratio of 80% and a maximum of 400%. Switching characteristics include a rise time of 3 µs and a fall time of 5 µs. Additional specifications list a reverse voltage of 6 V, power dissipation of 300 mW, and an operating temperature range from -55°C to +100°C.
Feature Summary
- Provides galvanic isolation between input and output circuits using light transmission.
- Utilizes an NPN phototransistor for digital signal switching applications.
- Designed for surface-mount assembly in compact electronic systems.
Applications
- Industrial control system signal isolation
- Power supply feedback loop isolation
- Microcontroller interface protection
Procurement Notes
Verify component authenticity through authorized Renesas distributors or certified partners. Confirm the specific suffix matches project requirements, as variations exist within the PS2561 family. Check current availability status, as this part may be subject to limited supply or discontinuation notices. Ensure compliance with RoHS directives and relevant safety standards before integration into final products.
Selection Notes
Select this component when a surface-mount solution is required for single-channel isolation with moderate current handling capabilities. Compare the 70 V collector-emitter voltage and 30 mA collector current limits against circuit demands. Consider the 5000 Vrms isolation rating for safety-critical designs. Evaluate the DIP-4 Gull Wing package dimensions against PCB layout constraints compared to through-hole alternatives.
Part Context
This device belongs to the PS2561A series of transistor output optocouplers. It shares functional similarities with other variants like the PS2561-1-A but differs in packaging and specific electrical ratings. The series is designed for general-purpose isolation tasks, offering a balance between performance and cost-effectiveness for industrial and consumer electronics applications requiring reliable signal transmission across isolated boundaries.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult official Renesas cross-reference guides for potential equivalents.
