PN4392_D27Z

Overview

The PN4392_D27Z is a single N-channel Junction Field-Effect Transistor (JFET) manufactured by onsemi. 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 current of 75 mA at zero gate-source voltage. The device features a maximum drain-source on-resistance of 60 Ohms and a power dissipation rating of 625 mW. It operates within a temperature range from -65°C to +150°C.

Feature Summary

• N-channel JFET configuration for signal processing applications
• Through-hole TO-92-3 packaging for standard board mounting
• Silicon-based construction for reliable operation

Applications

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

Procurement Notes

Verify the manufacturer designation carefully, as the PN4392 part number is historically associated with Central Semiconductor. Confirm that onsemi is the active supplier for this specific suffix variant. Check datasheets for pinout compatibility and parameter tolerances before integration into designs relying on legacy components.

Selection Notes

Select this component when an N-channel JFET with moderate current handling and high input impedance is required. The TO-92-3 package suits prototyping and low-volume production. Ensure the design accommodates the 60 Ohm on-resistance and 625 mW power dissipation limits under expected operating conditions.

Part Context

This component belongs to the broader category of small-signal field-effect transistors. While similar devices exist from other manufacturers, the PN4392 series specifically denotes an N-channel JFET. The D27Z suffix indicates specific packaging or tape-and-reel configuration details provided by the manufacturer.
