Procurement Notes

Verify the specific manufacturer designation, as sources list both Linear Integrated Systems, Inc. and Hitech Semiconductor for this part number. Confirm the exact package marking and datasheet version to ensure compatibility with your circuit requirements before procurement.

Selection Notes

Select this component when low noise and high stability are critical for dual-channel applications. The TO-71 package suits through-hole designs requiring robust mechanical mounting. Ensure the 60 V breakdown voltage meets system voltage constraints.

Part Context

This part belongs to the LS840 series of low-noise JFETs from Linear Integrated Systems. The series includes variants like the LS844 and is available in multiple packages including TO-71, TO-78, PDIP, and SOIC. It is designed for precision analog applications requiring matched dual transistor pairs.

Replacement Considerations

Check for direct substitutes within the LS840 series such as the LS844 if higher transconductance is needed. Verify pinout compatibility and electrical parameter overlaps with other dual N-channel JFETs in the TO-71 package.
