Overview
The PS2561DL1-1Y-N-A is a high-isolation voltage photocoupler manufactured by Renesas Electronics Corporation. It features a GaAlAs LED coupled to an NPN phototransistor output, housed in a wide-body DIP package. The device provides a collector-emitter breakdown voltage of 80V and a transfer ratio range of 100% to 300%. It operates with a forward current up to 15mA and offers an isolation voltage rating of 5000Vrms. The component is designed for robust signal transmission across isolated circuits.
Feature Summary
- High isolation voltage capability for safe circuit separation
- Wide operating temperature range for industrial reliability
- Standard DIP package configuration for easy integration
Applications
- Industrial automation control systems
- Power supply feedback loops
- Communication interface isolation
Procurement Notes
Verify the specific suffix 'N-A' against official Renesas documentation to confirm lead-free status and tape-and-reel packaging details. Ensure the ordering code matches the exact pinout and isolation requirements for your design. Cross-reference the datasheet revision date to guarantee compliance with current safety standards.
Selection Notes
Select this component when high isolation voltage and standard NPN output are required. Consider the CTR range and input forward voltage drop during biasing calculations. Verify that the package width accommodates your PCB creepage and clearance constraints. Check thermal dissipation limits if operating at maximum forward currents.
Part Context
This part belongs to the PS2561 series of single-channel photocouplers. It is commonly used in applications requiring galvanic isolation between low-voltage control logic and higher-voltage power stages. The series is known for its reliability in noisy environments and compliance with international safety certifications.
Replacement Considerations
Check for direct replacements such as the PS2561D-1-Y-V or PS2561L-1-F3 depending on packaging and reel specifications. Ensure substitute parts maintain the same isolation voltage and CTR characteristics. Verify pin compatibility before swapping components in existing designs.
