PN4392 TO-92 3L ROHS

Overview

The PN4392 is a single N-channel silicon Junction Field-Effect Transistor (JFET) manufactured by Central Semiconductor. It utilizes a TO-92-3 through-hole package and operates in depletion mode. Key electrical specifications include a gate-source breakdown voltage of 40 V, a gate-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 functions within an operating temperature range from -65°C to +150°C.

Feature Summary

N-channel silicon construction for reliable small-signal field-effect operation
Single-element configuration housed in a standard TO-92-3 through-hole package
Depletion mode functionality suitable for analog switching and amplification

Applications

Small signal amplification circuits
Analog switching applications
Low noise pre-amplifier stages

Procurement Notes

Verify the manufacturer designation carefully, as the PN4392 part number is primarily associated with Central Semiconductor. Confirm that the specific ordering suffix matches the required lead-free or tin/lead plating variant. Ensure the TO-92-3 package type aligns with the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a low-cost, through-hole N-channel JFET is required for general-purpose analog signal processing. Consider the 60 Ohm on-resistance and 625 mW power dissipation limits to ensure compatibility with the circuit's thermal and impedance constraints. Verify that the 40 V breakdown voltage provides sufficient margin for the intended operating conditions.

Part Context

The PN4392 belongs to the family of small-signal junction field-effect transistors designed for discrete semiconductor applications. Manufactured using silicon technology, it serves as a fundamental active component in electronic designs requiring high input impedance and low noise characteristics. The TO-92 package facilitates easy integration into legacy and modern through-hole assembly processes.
