Overview
The PS2561DL2-1Y-V-F3-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and operates in a DIP-4 Gull Wing package suitable for surface mount technology. The device provides an isolation voltage of 5000 Vrms, ensuring robust electrical separation between input and output circuits. Key electrical parameters include a minimum current transfer ratio (CTR) of 50% and a maximum CTR of 400%. The forward current rating is 40 mA with a forward voltage of 1.4 V. The collector-emitter saturation voltage is limited to 300 mV, while the maximum collector current is 50 mA. The component supports a maximum collector-emitter voltage of 80 V, with switching times of 3 µs rise and 5 µs fall.
Feature Summary
- Provides high-voltage isolation capability through a dedicated insulating barrier between the infrared LED and phototransistor.
- Features a compact surface-mount DIP-4 Gull Wing package designed for automated assembly processes.
- Delivers consistent signal transmission via an NPN phototransistor output stage optimized for digital logic interfacing.
Applications
- Signal isolation in industrial control systems
- Interface circuits for microcontroller-based designs
- Power supply feedback loops requiring galvanic isolation
Procurement Notes
Verify the specific suffix codes against official Renesas documentation to confirm exact binning and tape-and-reel specifications. Ensure compatibility with RoHS directives if required by your manufacturing standards. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when a surface-mount solution with moderate speed and high isolation voltage is required. Compare the CTR range and switching speeds against system timing requirements. Consider the thermal characteristics and power dissipation limits relative to the operating environment and PCB layout constraints.
Part Context
This device belongs to the PS2561 series of transistor output optocouplers from Renesas Electronics. The series is engineered for general-purpose isolation applications where reliable signal transmission across isolated boundaries is critical. The DL2 variant specifically denotes the surface-mount package configuration within this product family.
Replacement Considerations
Consult official substitution guides for equivalent components. Verify pinout compatibility and electrical parameter overlaps before replacing existing designs with alternative optocouplers.
