PN4392 TRE PBFREE

Overview

The PN4392 TRE PBFREE is a single 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 parameters include a gate-source breakdown voltage of 40 V, a drain-source on-resistance of 60 Ohms, and a power dissipation rating of 625 mW. The device supports an operating temperature range from -65°C to +150°C.

Feature Summary

• N-channel JFET configuration for signal processing
• Silicon-based construction for thermal stability
• Through-hole mounting capability

Applications

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

Procurement Notes

Verify the specific suffix 'TRE PBFREE' against the manufacturer's datasheet to confirm lead-free compliance and reel packaging specifications. Ensure the procurement channel provides official documentation matching the Central Semiconductor part number to avoid counterfeit components or incorrect variant substitutions.

Selection Notes

Select this component when a through-hole N-channel JFET with a 40V breakdown voltage is required. Consider the 60 Ohm on-resistance and 625 mW power dissipation limits during circuit design. Verify that the TO-92-3 package fits the board layout constraints compared to surface-mount alternatives like the CMPF4392.

Part Context

This part belongs to the PN4392 series of N-channel JFETs produced by Central Semiconductor. It serves as a discrete semiconductor solution for analog electronics, distinct from bipolar transistors or MOSFETs. The product line focuses on general-purpose amplification and switching tasks within the specified voltage and current ratings.

Replacement Considerations

The CMPF4392 TR PBFREE is a verified equivalent offering identical electrical characteristics but in a SOT-23 surface-mount package. Substitution requires PCB re-layout to accommodate the different footprint and mounting style.
