Overview
The PS2561DL-1Y-V-F3-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and operates in a surface-mount DIP-4 gull wing package. The device provides 5000 Vrms isolation voltage with a maximum collector-emitter voltage of 80 V and a maximum collector current of 50 mA. Key electrical parameters include a forward current of up to 40 mA, a forward voltage of 1.4 V, and a CTR range of 50% to 400%. Switching times are characterized by a typical rise time of 3 µs and fall time of 5 µs. It supports an operating temperature range from -55°C to +110°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits for signal transmission.
- Utilizes an NPN phototransistor output stage for digital switching applications.
- Designed for surface-mount assembly using a compact four-pin gull wing package.
Applications
- Programmable logic controller (PLC) I/O modules
- Power supply feedback loops
- FA/OA equipment interface circuits
Procurement Notes
Verify the specific suffix 'V' against official Renesas documentation to confirm lead-free status and safety approvals. Confirm package type matches the required surface-mount footprint. Check RoHS compliance status directly from the manufacturer datasheet before integration into designs requiring restricted substance limitations.
Selection Notes
Select this component when high isolation voltage is required in a small surface-mount form factor. Ensure the application current requirements fall within the 50 mA collector current limit. Verify that the 5000 Vrms insulation rating meets the safety standards of the target system. Consider the switching speed characteristics if high-frequency signal transmission is necessary.
Part Context
This part belongs to the PS2561 series of transistor output optocouplers. The series is designed for general-purpose isolation in industrial and consumer electronics. The DL variant specifically denotes the surface-mount package configuration. Renesas continues to support this family for legacy and new designs requiring reliable galvanic isolation.
Replacement Considerations
PS2561DL-1Y-F3-A is a confirmed substitute within the same series offering identical functional specifications and package dimensions. Verify pinout compatibility and electrical ratings match the original design requirements before substitution.
