Overview
The PS2561D-1Y-V-L-A is a transistor output optocoupler manufactured by Renesas Electronics. It features a single channel with an NPN phototransistor output and DIP-4 through-hole packaging. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and an isolation voltage of 5000 Vrms. The forward current rating is 40 mA with a typical forward voltage of 1.2 V. The current transfer ratio ranges from 130% to 260%. Operating temperature spans from -55°C to +110°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using optical coupling technology.
- Integrates a GaAs light emitting diode with an NPN silicon phototransistor for signal transmission.
- Designed for robust performance across a wide industrial operating temperature range.
Applications
- Industrial automation control systems
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix 'V-L-A' against official Renesas documentation to confirm package variant and compliance status. Ensure compatibility with existing PCB footprints for DIP-4 configurations. Confirm availability through authorized distributors as stock levels vary. Validate RoHS compliance requirements for the target assembly process before procurement.
Selection Notes
Select this component when high isolation voltage and wide temperature operation are required in a DIP package. Compare current transfer ratio specifications against load requirements. Ensure the 80 V collector-emitter voltage meets circuit switching needs. Verify that the 40 mA forward current limit aligns with drive source capabilities.
Part Context
This part belongs to the PS2561 series of transistor output optocouplers. The series includes variants such as PS2561-1, PS2561L-1, and PS2561DL-1, which differ primarily in package type and pin configuration. The D-series denotes DIP packaging, while L-series indicates surface mount options.
Replacement Considerations
PS2561D-1Y-A is a related variant within the same family. Verify pinout and electrical parameter equivalence before substitution. Check datasheet revisions for any changes in mechanical dimensions or material composition.
