PS2911-1-F3-K-AX

Overview

The PS2911-1-F3-K-AX is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and utilizes a 4-pin SSOP package for surface mount installation. The device provides an isolation voltage of 2500 Vrms, with a maximum collector-emitter voltage of 40 V and a maximum collector current of 40 mA. Key electrical parameters include a forward current of 50 mA, a forward voltage of 1.3 V, and a power dissipation of 180 mW. The current transfer ratio ranges from 100% to 400%, while rise and fall times are specified at 5 µs and 10 µs respectively. Operating temperatures span from -55°C to +100°C.

Feature Summary

Provides galvanic isolation between input and output circuits using optical transmission.
Features an NPN phototransistor output stage for digital signal switching applications.
Designed for surface mount technology with a compact 4-pin SSOP footprint.

Applications

Industrial control systems requiring signal isolation
Measurement equipment input stages
Power supply feedback loops

Procurement Notes

Verify the specific suffix 'K' against official Renesas documentation to confirm lead frame plating or tape-and-reel specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet. Ensure the component is suitable for new designs as some variants in this series may carry NRND status. Cross-reference the exact part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a single-channel isolation barrier is required with moderate speed requirements. The 40 V collector-emitter voltage rating suits low-voltage logic interfacing. Verify that the 100% to 400% current transfer ratio meets the drive requirements of the downstream load. Consider the thermal dissipation limits within the SSOP package for high-duty cycle operations.

Part Context

This part belongs to the PS2911 series of transistor output optocouplers. The series is characterized by high current transfer ratios and small package sizes. The PS2911-1 variant specifically denotes a single-channel configuration. The F3 suffix typically indicates specific packaging or material attributes defined by the manufacturer.
