U405 TO-71 6L ROHS

Overview

The U405 TO-71 is a low noise, low drift monolithic dual N-channel JFET manufactured by Linear Integrated Systems. It features a typical pinch-off voltage of 2.5V and an input-referred noise density of 6nV/√Hz at 10Hz. The device exhibits a gate-source voltage drift of 10µV/°C over temperature.

Feature Summary

Monolithic dual N-channel JFET architecture
Low noise performance for precision signal paths
Minimal gate-source voltage drift across temperature ranges

Applications

Precision analog front-end circuits
Low-noise amplifier stages
High-impedance sensor interfaces

Procurement Notes

Verify the manufacturer source carefully as multiple vendors list similar part numbers with conflicting descriptions. Confirm the specific package style matches the TO-71 requirement and ensure RoHS compliance status aligns with project specifications before procurement.

Selection Notes

Select this component when low input noise and stable bias characteristics are critical. The dual configuration allows for matched pairs in differential applications. Ensure the TO-71 metal can package fits the thermal and mechanical constraints of the design.

Part Context

This component belongs to a family of monolithic dual JFETs designed for high-performance analog applications. It serves as a replacement or alternative to older discrete JFET pairs, offering improved matching and stability due to its integrated construction on a single silicon die.

Replacement Considerations

LSU401 and LS3954-8 are documented equivalents within the same functional family. Verify pinout compatibility and electrical parameter tolerances against the original design requirements when substituting.
