Overview
The PS2561FL-1Y-K-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and utilizes a 4-SMD gull-wing package for surface mount installation. The device provides an isolation voltage of 5000 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and a typical forward voltage of 1.2 V. The DC forward current rating is 30 mA. The current transfer ratio ranges from 300% to 600% at a forward current of 5 mA. Typical switching times are 5 µs for rise time and 7 µs for fall time.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using optical transmission.
- Features a compact surface-mount package suitable for automated assembly processes.
- Delivers robust signal transmission with defined current transfer characteristics for reliable logic interfacing.
Applications
- Signal isolation in industrial control systems
- Interface circuits for microprocessor-based systems
- Power supply feedback loops
Procurement Notes
Verify the specific suffix K-A against official Renesas documentation to confirm tape-and-reel packaging configuration. Ensure the component status is reviewed as some sources indicate it may be not recommended for new designs. Cross-reference the manufacturer part number directly with the datasheet to validate all electrical ratings before integration.
Selection Notes
Select this component when surface-mount technology is required for single-channel isolation. Consider the 30 mA forward current limit and the specific CTR range of 300% to 600%. Verify that the 4-SMD gull-wing footprint matches the PCB layout constraints. Confirm compatibility with the target operating temperature range of -55°C to 110°C.
Part Context
This part belongs to the PS2561 family of transistor output optocouplers. It shares core isolation specifications with other variants but differs in package type and manufacturing suffixes. The FL designation indicates the surface-mount gull-wing form factor. It serves as a digital isolation solution within the broader portfolio of Renesas electronic components.
Replacement Considerations
PS2561FL-1Y-A is listed as a parameter equivalent substitute. Other variants such as PS2561DL-1Y-F3-A or PS2561L-1-A may offer similar isolation but differ in package style or current ratings. Always verify pinout and mechanical dimensions before substitution.
