2N4393 TO-18 3L ROHS

Jfets Overview

The 2N4393 is an N-channel JFET manufactured by Linear Integrated Systems, Inc. It utilizes Silicon technology and is housed in a TO-18-3 hermetically sealed through-hole package. The device features a Gate-to-Source breakdown voltage of -40 V and a Drain-to-Source saturation current (IDSS) of 5 mA. Its Gate-to-Source cutoff voltage (VGS(off)) is specified at -0.5 V minimum. This component is designed for low-noise applications with a typical noise density of 1.2 nV/√Hz.

Jfets Feature Summary

Hermetically sealed TO-18 package suitable for military applications
Low noise performance with 1.2 nV/√Hz typical density
Fast switching capability

Jfets Applications

Low on-resistance analog switches
Chopper circuits
Commutator designs

Jfets Procurement Notes

Verify the manufacturer designation as Linear Integrated Systems, Inc., noting that InterFet is the original designer. Confirm the specific suffix indicates RoHS compliance and the TO-18-3 leaded package. Ensure the part number matches the exact electrical parameters required for your circuit design before ordering.

Jfets Selection Notes

Select this component when a low cutoff voltage below 0.5 V is required for low-level power supplies. The TO-18 package provides environmental protection necessary for harsh conditions. Verify that the -40 V breakdown voltage meets the system's maximum operating limits.

Jfets Part Context

This part belongs to the 2N4391, 2N4392, and 2N4393 family of N-channel JFETs. While originally designed by InterFet, it is now produced under license by Linear Integrated Systems. The 2N4393 variant is distinguished by its very low cutoff voltage compared to the other members of the series.
