U403 TO-71 6L

Overview

The U403 TO-71 6L is a monolithic dual N-channel JFET switch manufactured by Linear Integrated Systems. It features low noise and low drift characteristics, with a typical gate-source voltage drift of 10µV/°C and input noise of 6nV/√Hz at 10Hz. The device has a typical pinch-off voltage of 2.5V. It is housed in a TO-71 package.

Feature Summary

Monolithic dual N-channel JFET configuration
Low noise performance suitable for precision applications
Low temperature drift for stable operation

Applications

Precision analog switching
Low noise signal conditioning circuits
Instrumentation front ends

Procurement Notes

Verify the manufacturer designation as Linear Integrated Systems or its successor entities like Micross Components. Confirm the specific suffix 'TO-71 6L' matches the required pinout and package style. Check datasheets for discontinuation status and potential cross-references such as LSU401 or 2N3954 if original stock is unavailable.

Selection Notes

Select this component for applications requiring low charge injection and minimal offset voltage drift. Ensure the supply voltage and signal levels remain within the specified limits to maintain the low noise and low drift specifications provided in the official documentation.

Part Context

This part belongs to a family of monolithic dual N-channel JFET switches designed for high-performance analog applications. Similar parts include the U401, U402, and U405, which share comparable low noise and low drift characteristics but may differ in specific electrical parameters or packaging options.

Replacement Considerations

Potential replacements include the LSU401 from Micross Components or the 2N3954. Verify pin compatibility and electrical parameter equivalence before substitution.
