Jfets Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing from distributors. Confirm RoHS compliance status with the manufacturer or authorized suppliers prior to procurement. Ensure the ordering quantity aligns with the supplier's minimum order requirements and reel specifications. Cross-reference the datasheet revision date to ensure compatibility with design specifications.

Jfets Selection Notes

Select this component for designs requiring a robust N-JFET with high-temperature capability up to 200°C. The 30V breakdown voltage suits low-voltage analog applications. Consider the 40 Ohm on-resistance for impedance matching requirements. Verify that the surface-mount package fits the PCB footprint constraints compared to through-hole alternatives like the 2N4859UB.

Jfets Part Context

This part belongs to the Microchip Technology JFET family, specifically the 2N48xx series. These transistors are silicon-based devices intended for general-purpose analog applications. The series offers various configurations and packages, with the 2N4860UB/TR representing a specific surface-mount variant optimized for automated assembly processes.

Jfets Replacement Considerations

The MQ2N4859UB/TR is a documented substitute within the same product family. Both are N-channel JFETs with similar 30V ratings. However, the MQ2N4859UB/TR has a higher drain current of 175 mA and lower on-resistance of 25 Ohms. Verify pinout compatibility and thermal characteristics before substitution.
