2N4416A

Jfets Overview

The Microchip Technology 2N4416A is an N-channel Junction Field-Effect Transistor (JFET) designed for sensitive analog applications. It features a typical gate leakage current of 10 pA at room temperature and a typical noise figure of 4 nV/√Hz. The device operates with a gate-to-source breakdown voltage (BVgss) of -35 V, which is higher than the standard 2N4416 variant. Key electrical parameters include a drain-to-source saturation current (IDSS) minimum of 5 mA and a gate-to-source cutoff voltage (VGS(off)) maximum of -2.5 V. Forward transconductance (Gfs) is specified at a minimum of 4500 µS.

Jfets Feature Summary

• Hermetically sealed TO-72 package suitable for military and high-reliability environments
• Ultra-low gate leakage current for minimal signal distortion
• Low noise performance optimized for sensitive RF front-ends

Jfets Applications

• Sensitive mixer circuits
• VHF amplifier designs
• Military-grade electronic systems

Jfets Procurement Notes

Verify the specific manufacturer source, as Interfet produces this component under the Microchip umbrella. Confirm package availability, as options include through-hole TO-72, surface mount SOT-23, and bare die. Check for RoHS compliance status depending on the specific production lot and ordering suffix. Ensure the selected bin matches the required IDSS or VGS(off) specifications for the target circuit design.

Jfets Selection Notes

Select the 2N4416A over the standard 2N4416 when a higher gate-to-source breakdown voltage of -35 V is required. Consider the TO-72 package for hermetic sealing needs in harsh environments. Evaluate the SOT-23 option if surface mount technology is necessary. Verify that the minimum IDSS of 5 mA meets the biasing requirements of the intended application.

Jfets Part Context

This component belongs to the Interfet JFET family, now part of Microchip Technology's portfolio. It is specifically engineered for high-performance analog signal processing where low noise and high input impedance are critical. The 'A' suffix denotes the enhanced breakdown voltage characteristic compared to the base model.

Jfets Replacement Considerations

Public confirmed substitute part numbers: PN4416A (Through-Hole), SMP4416A (Surface Mount). These variants share identical electrical characteristics but differ in packaging format.
