2N4416AUB/TR

Jfets Overview

The Microchip Technology 2N4416AUB/TR is an N-channel Junction Field-Effect Transistor (JFET) designed for sensitive mixer and VHF amplifier applications. It features a gate leakage current typically less than 10 pA at room temperature and offers a higher breakdown voltage compared to the standard 2N4416 variant. The device utilizes Interfet N0026S geometry and is RoHS compliant. It is supplied in a surface-mount SOT-23 package on a 7-inch tape and reel, with a maximum quantity of 3,000 pieces per reel.

Jfets Feature Summary

• Low noise performance with typical input noise density of 4 nV/√Hz
• Ultra-low gate leakage current typically below 10 pA
• Hermetically sealed TO-72 package option available for military suitability

Jfets Applications

• Sensitive mixer circuits
• VHF amplifier designs

Jfets Procurement Notes

Verify the specific suffix 'UB/TR' against official Microchip documentation to confirm it denotes the SOT-23 surface mount package on a 7-inch tape and reel. Ensure the ordering quantity aligns with the manufacturer's maximum reel size of 3,000 pieces. Cross-reference the part number with the Interfet product folder to validate electrical characteristics and packaging details before procurement.

Jfets Selection Notes

Select this component for applications requiring low noise and high input impedance in VHF ranges. The 'A' variant provides a higher breakdown voltage than the standard 2N4416. Consider the SOT-23 package for surface mount assembly or TO-72 for hermetic military requirements. Verify that the required gate leakage and noise specifications meet the design constraints.

Jfets Part Context

This JFET belongs to the Interfet family of N-channel devices, known for specialized geometries like N0026S. It is distinct from general-purpose transistors due to its ultra-low leakage and noise characteristics. The product line includes through-hole, surface mount, and bare die options to accommodate various manufacturing and environmental needs.

Jfets Replacement Considerations

The standard 2N4416 serves as a baseline alternative but lacks the higher breakdown voltage of the 'A' variant. PN4416 and SMP4416 are equivalent through-hole and surface mount counterparts respectively. Verify pinout compatibility and electrical limits when substituting.
