2N6428 TRE PBFREE

Overview

The 2N6428 TRE PBFREE is an N-channel Junction Field-Effect Transistor (JFET) manufactured by Central Semiconductor Corp. It utilizes silicon technology and is housed in a TO-92-3 through-hole package. Key electrical specifications include a gate-source breakdown voltage of 40 V, a drain-source cutoff voltage of 5 V, and a drain-source on-resistance of 60 Ohms at zero gate-source voltage. The device supports a maximum power dissipation of 625 mW and operates within a temperature range of -65°C to +150°C.

Feature Summary

• Single N-channel JFET configuration for signal processing applications
• Silicon-based construction ensuring stable performance across wide temperature ranges
• Through-hole mounting compatibility with standard TO-92-3 leaded packages

Applications

• Low-noise amplifier circuits
• High-impedance input stages
• Analog switching applications

Procurement Notes

Verify the specific datasheet version for the PN4392 series, as the 2N6428 designation often corresponds to this family in manufacturer catalogs. Confirm RoHS compliance status and lead-free packaging requirements directly with the supplier. Ensure the ordering suffix matches the required reel or bulk quantity format specified in the official product documentation before finalizing purchase orders.

Selection Notes

Select this component when a low-noise N-channel JFET with high input impedance is required for analog signal paths. The TO-92-3 package facilitates easy integration into prototyping boards and legacy designs utilizing through-hole technology. Evaluate the 60 Ohm on-resistance and 40 V breakdown limits against circuit voltage and current constraints to ensure reliable operation under all expected load conditions.

Part Context

This part belongs to the Central Semiconductor discrete transistor portfolio, specifically within the JFET category. It serves as a specialized active component for precision analog electronics, distinct from general-purpose bipolar junction transistors. The manufacturer provides technical documentation detailing absolute maximum ratings and electrical characteristics to support circuit design and validation processes.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic JFET replacements may differ in noise figures or pin configurations. Verify that any alternative part maintains compatible package dimensions and electrical parameters for direct board replacement without schematic modification.
