Overview
The PS2811-1-V-F3-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates an AlGaAs LED and an NPN phototransistor in a thin SSOP-4 package. Key electrical parameters include a collector-emitter breakdown voltage of 40 V, a maximum forward current of 50 mA, and an isolation voltage of 2500 Vrms. The device operates within a temperature range of -55 °C to +100 °C, with a typical current transfer ratio of 100% and power dissipation of 180 mW.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits via optical coupling.
- Features a shielded plastic SSOP-4 package designed for high-density surface-mount applications.
- Ensures reliable signal transmission with low dark current and defined switching characteristics.
Applications
- Industrial control systems requiring galvanic isolation
- Measurement and testing equipment interfaces
- Power supply feedback loops
Procurement Notes
Verify the specific suffix 'V' against official Renesas documentation to confirm lead-free status and RoHS compliance details. Ensure the SSOP-4 package dimensions match the target PCB footprint. Confirm that the 40 V collector-emitter voltage rating meets the circuit requirements. Check for any specific UL or CSA safety approvals required for the end application.
Selection Notes
Select this component when a single-channel isolation solution with a 40 V output voltage rating is required. The thin SSOP-4 package is suitable for space-constrained designs. Verify that the 100% typical CTR aligns with the driving circuit capabilities. Consider the operating temperature range of -55 °C to +100 °C for environmental suitability.
Part Context
This part belongs to the PS2811 series of single-channel transistor output optocouplers from Renesas. The series is characterized by its compact SSOP-4 packaging and high isolation voltage capabilities. It serves as a standard component for basic digital signal isolation tasks in various electronic systems.
Replacement Considerations
Cross-reference with PS2811-1-K-A or PS2811-1-L-A for similar pinouts and electrical characteristics. Verify package compatibility and ensure equivalent isolation ratings before substitution.
