PS2911-1-V-F3-L-AX

Overview

The PS2911-1-V-F3-L-AX is a single-channel transistor output optocoupler manufactured by Renesas Electronics Corporation. It features a 4-Mini-Flat surface-mount package and provides an isolation voltage of 2500Vrms. The device utilizes an NPN phototransistor output with a maximum collector-emitter voltage of 40V and a continuous collector current of 40mA. Key electrical parameters include a typical forward voltage of 1.1V, a maximum DC forward current of 50mA, and a saturation voltage of 300mV. The component operates within a temperature range of -55°C to 100°C and offers a current transfer ratio ranging from 100% to 400% at a forward current of 1mA.

Procurement Notes

Verify the specific suffix 'L' against official Renesas documentation to confirm lead frame material or plating specifications, as standard datasheets may not explicitly detail this variant's unique physical attributes. Ensure the requested quantity aligns with available packaging options such as cut tape or reel. Confirm RoHS compliance status directly with the manufacturer or authorized distributor prior to finalizing procurement orders.

Selection Notes

Select this component when a low-profile surface-mount solution is required for single-channel isolation applications. The 40V output rating and 40mA current capacity are suitable for driving standard logic inputs or small loads. Consider the 2500Vrms isolation rating for safety requirements in mains-connected equipment. Verify that the Mini-Flat footprint matches the target PCB layout constraints before integration into the design.

Part Context

This part belongs to the PS2911 series of transistor output optocouplers from Renesas Electronics. The series is characterized by high current transfer ratio consistency and reliability for general-purpose isolation tasks. The PS2911-1-V-F3-L-AX represents a specific configuration within this family, distinguished by its particular packaging and terminal finish specifications defined by the manufacturer's ordering codes.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic equivalents may differ in isolation voltage ratings or package dimensions. Verify pinout compatibility and electrical parameter margins before substituting to ensure circuit functionality remains intact.
