PS2811-1-F3-M-A

Overview

The PS2811-1-F3-M-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and utilizes a thin SSOP-4 package. Key electrical parameters include a maximum collector-emitter voltage of 40 V, a maximum forward current of 50 mA, and a typical current transfer ratio of 100%. The device supports an insulation voltage of 2500 Vrms and operates within a temperature range of -55 °C to +100 °C.

Feature Summary

• Provides high-voltage isolation between input and output circuits
• Features a compact thin plastic SSOP-4 package for space-constrained designs
• Includes shielded structure to minimize ambient light interference

Applications

• Industrial control systems requiring signal isolation
• Power supply feedback loops
• Microcontroller interface circuits

Procurement Notes

Verify the specific suffix F3-M-A against official Renesas documentation to confirm pinout and packaging variations. Ensure compliance with RoHS directives as indicated in component records. Cross-reference datasheets for thermal derating curves before finalizing procurement specifications.

Selection Notes

Select this component when a single-channel isolation solution with a 40 V collector-emitter rating is required. The SSOP-4 package suits applications needing surface-mount assembly with limited board space. Verify that the 100% CTR meets the logic level requirements of the receiving circuit.

Part Context

This part belongs to the PS2811 series of transistor output optocouplers from Renesas. The series is designed for general-purpose isolation tasks. The PS2811-1 variant specifically denotes a single-channel configuration, distinguishing it from multi-channel counterparts like the PS2811-4.

Replacement Considerations

Consult official substitution guides for equivalent parts. Verify pin compatibility and electrical ratings before replacing.
