Overview
The PS2561DL2-1Y-H-A is a transistor output optocoupler manufactured by Renesas Electronics Corporation. It features a single channel with an NPN phototransistor output and operates at an isolation voltage of 5000 Vrms. The device supports a maximum collector current of 50 mA and a maximum collector-emitter voltage of 80 V. Key electrical parameters include a forward current of 40 mA, a typical forward voltage of 1.2 V, and a current transfer ratio ranging from 50% to 400%. The unit utilizes a 4-SMD gull wing package for surface mount installation.
Feature Summary
- Integrates a GaAs light emitting diode with an NPN silicon phototransistor for signal isolation
- Provides high insulation capability with a rated isolation voltage of 5000 Vrms
- Designed for surface mount applications using a compact 4-SMD gull wing package
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal transmission between microcontrollers and high-voltage circuits
Procurement Notes
Verify the specific suffix H-A against official Renesas documentation to confirm package type and tape/reel specifications. Ensure compatibility with RoHS3 standards and check moisture sensitivity level requirements for your assembly process. Confirm that the 4-SMD gull wing footprint matches your PCB design constraints before finalizing procurement.
Selection Notes
Select this component when a surface mount solution is required for single-channel isolation with high voltage withstand capabilities. Consider the 50 mA output current limit and 80 V collector-emitter voltage rating for circuit design. Evaluate the current transfer ratio range to ensure sufficient gain for your specific logic interface requirements.
Part Context
This part belongs to the PS2561 series of optically coupled isolators produced by Renesas Electronics. The series typically includes various package options such as DIP and SMD variants. The DL2 designation indicates a specific lead form or package configuration within the broader product family designed for modern surface mount manufacturing processes.
Replacement Considerations
Direct substitutes may include PS2561DL2-1Y-F3-A or PS2561DL2-1Y-V-F3-A from Renesas, provided pinout and electrical characteristics align. Verify package dimensions and thermal performance before swapping components in existing designs.
