Overview
The PS2561D-1Y-W-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and operates in a DIP-4 package with through-hole mounting. The device provides 5000 Vrms insulation voltage and supports a maximum collector current of 50 mA. Key electrical parameters include a forward current of 40 mA, a forward voltage of 1.2 V, and a collector-emitter saturation voltage of 300 mV. The typical current transfer ratio is 160%, with a range from 130% to 260%. Switching characteristics include a rise time of 3 µs and a fall time of 5 µs. It operates within a temperature range of -55°C to +110°C.
Feature Summary
- Provides high-voltage isolation between input and output circuits
- Features fast switching speeds for signal transmission
- Offers robust thermal performance across wide temperature ranges
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix 'W' against official Renesas documentation to confirm lead-free status or specific tape-and-reel packaging requirements. Ensure compatibility with RoHS directives if applicable. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and lifecycle status before finalizing procurement plans.
Selection Notes
Select this component when a single-channel transistor output optocoupler with high isolation voltage is required. Consider the 5000 Vrms rating for safety-critical applications. Evaluate the 160% typical CTR against load requirements. Compare switching times against signal frequency needs. Verify package compatibility with existing PCB footprints.
Part Context
This part belongs to the PS2561 series of transistor output optocouplers. The series is designed for general-purpose isolation applications. Variants differ primarily in packaging (DIP vs. SMD) and specific electrical tolerances. The PS2561D variant typically denotes specific pinout or performance characteristics within the family.
Replacement Considerations
Direct substitutes may include other PS2561 variants with compatible pinouts. Check datasheets for matching CTR ranges and isolation voltages. Ensure replacement parts meet the same thermal and electrical specifications.
