Overview
The PS2911-1-F3-AX is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum collector-emitter voltage of 40V, a maximum collector current of 40mA, and a forward current of 50mA. The device provides 2500Vrms isolation voltage with a typical forward voltage of 1.1V. Current transfer ratio ranges from 100% to 400% at 1mA input. Rise and fall times are typically 5µs and 10µs respectively, with a power dissipation rating of 180mW.
Feature Summary
- Provides galvanic isolation between input and output circuits using an NPN phototransistor configuration.
- Designed for surface mount installation in compact SSOP-4 packages.
- Capable of operating reliably across extended industrial temperature ranges.
Applications
- Signal isolation in microcontroller interface circuits
- Gate drive isolation for power switching applications
- Industrial control system signal transmission
Procurement Notes
Verify the specific suffix F3-AX against official Renesas documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents. Ensure the component source is authorized to avoid counterfeit risks. Check for any recent Product Change Notifications (PCNs) regarding material or manufacturing site changes that may affect compatibility.
Selection Notes
Select this component when a single-channel isolation solution with moderate speed is required. The 40V collector-emitter voltage suits low-voltage logic interfacing. Verify that the 5µs rise time meets the application's switching frequency requirements. Compare the CTR range against the driving circuit's ability to maintain saturation under varying conditions and temperatures.
Part Context
This part belongs to the PS2911 series of transistor output optocouplers. It shares functional similarities with other members like PS2911-1-V-F3-AX but differs in packaging and specific electrical tolerances defined by the suffix. The series is designed for general-purpose isolation tasks in consumer and industrial electronics.
Replacement Considerations
PS2911-1-V-F3-AX offers similar electrical characteristics but utilizes a Mini-Flat package instead of SSOP. Cross-reference pinouts and thermal performance before substitution. Other PS2911 variants may differ in CTR or voltage ratings; verify datasheet alignment for direct replacement.
