Overview
The PS2561DL-1Y-V-W-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and utilizes a DIP-4 package for through-hole mounting. The device provides high isolation voltage of 5000 Vrms between input and output circuits. 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 at a maximum forward current of 40 mA. The component operates within a temperature range of -55°C to +110°C.
Feature Summary
- Provides galvanic isolation via optical transmission between input and output circuits
- Features an NPN phototransistor output stage for digital signal switching
- Designed for through-hole integration using a standard four-pin DIP configuration
Applications
- Industrial control systems requiring circuit isolation
- Signal transmission in noisy electrical environments
- Power supply feedback loops for voltage regulation
Procurement Notes
Verify the exact suffix against official Renesas documentation to confirm pinout and packaging specifications. Ensure compatibility with existing PCB footprints before procurement. Confirm RoHS compliance status for specific manufacturing batches. Check for any recent product change notices that may affect lead times or material composition. Validate supplier authenticity to prevent counterfeit components.
Selection Notes
Select this component when high isolation voltage is required for safety-critical applications. Consider the through-hole package for robust mechanical stability in industrial settings. Evaluate the current transfer ratio requirements against the driving circuit capabilities. Ensure the operating temperature range meets the environmental conditions of the final assembly.
Part Context
This part belongs to the PS2561 series of transistor output optocouplers from Renesas Electronics. The series is designed for general-purpose isolation applications. Variations in the suffix typically denote differences in packaging style, such as surface mount versus through-hole, or specific testing criteria. The DL variant often indicates a specific lead form or package type within the broader family.
Replacement Considerations
Consult official Renesas substitution guides for verified equivalents. Cross-reference pinouts and electrical characteristics carefully. Verify that alternative components meet the same isolation voltage and current ratings.
