2N4416A TO-72 4L ROHS

Jfets Overview

The Linear Integrated Systems 2N4416A is an N-channel JFET designed for high-frequency amplifier applications. It features a TO-72 hermetic package and offers a gate-to-source breakdown voltage of -35V, compared to -30V for the standard 2N4416. Key electrical parameters include a typical gate leakage current of 0.1nA at -20V, a saturation current (IDSS) ranging from 5mA to 15mA, and a forward transconductance (gfs) between 4000µS and 7500µS. The device exhibits a low equivalent input noise voltage of 6nV/√Hz at 1kHz. At 400MHz, it provides a power gain of up to 10dB with a noise figure as low as 4dB under specified bias conditions.

Jfets Feature Summary

• Hermetically sealed TO-72 metal can package suitable for demanding environments
• Ultra-low gate leakage current ensuring minimal signal interference
• High forward transconductance supporting efficient amplification
• Low noise figure optimized for sensitive RF front-end circuits

Jfets Applications

• Very High Frequency (VHF) amplifiers
• Sensitive mixer designs
• Low-noise RF signal processing stages

Jfets Procurement Notes

Verify that the specific part number matches the required variant, as the 'A' suffix denotes a higher breakdown voltage (-35V) compared to the standard version. Confirm the package type corresponds to the design requirements, noting that while the TO-72 is standard, other packages like SOT-23 may exist for related variants. Ensure compliance with RoHS directives if lead-free soldering processes are mandated by the assembly line specifications.

Jfets Selection Notes

Select the 2N4416A over the standard 2N4416 when circuit designs require a higher gate-to-source breakdown voltage of -35V rather than -30V. Consider the TO-72 package for applications requiring hermetic sealing or military-grade reliability standards. Evaluate the noise figure and gain characteristics at the target operating frequency to ensure they meet the system's sensitivity and amplification requirements.
