Jfets datasheet and documents for 2N4392UB/TR
Jfets Overview
The 2N4392UB/TR is a Silicon N-channel Junction Field-Effect Transistor (JFET) manufactured by Microchip Technology. It utilizes the TO-18-3 metal can package for through-hole mounting. The device operates with a drain-source breakdown voltage of 40V and a gate-source cutoff voltage ranging from -0.5V to -6V. Key electrical characteristics include a maximum drain current of 10mA, a typical forward transconductance of 5000µmhos at VDS=10V and ID=1mA, and a low input leakage current of 1nA. The component supports an operating temperature range from -65°C to +175°C.
Jfets Feature Summary

Jfets Procurement Notes
Verify the specific suffix designation against official Microchip documentation to confirm tape-and-reel packaging requirements. Ensure that the requested quantity aligns with manufacturer minimum order specifications. Cross-reference the Mouser part number 579-MQ2N4392UB or similar identifiers to validate current availability status before finalizing procurement plans.
Jfets Selection Notes
Select this component when designing circuits requiring high input impedance and low noise figures in radio frequency environments. Compare the specified transconductance and breakdown voltage limits against circuit requirements to ensure adequate headroom. Consider the TO-18-3 package constraints regarding thermal dissipation and physical footprint during the layout phase.
Jfets Part Context
This JFET belongs to the standard discrete transistor category within Microchip's portfolio. It serves as a specialized active component distinct from bipolar junction transistors or MOSFETs. The device is engineered primarily for analog signal processing tasks where linearity and noise performance are critical design parameters.
Jfets Replacement Considerations
Consult official substitution guides for equivalent N-channel JFETs with matching pinouts and electrical ratings. Verify that alternative components meet the same hermetic sealing standards if used in harsh environments.
