PN4391 TO-92 3L ROHS

Overview

The PN4391 is a small-signal N-channel Junction Field-Effect Transistor (JFET) manufactured by Linear Integrated Systems, Inc. It is housed in a TO-92 three-lead cylindrical plastic package designed for through-hole mounting. The device operates in depletion mode and utilizes silicon technology. Key electrical characteristics include a maximum drain-source breakdown voltage of 60V, a gate-source breakdown voltage of ±25V, and a continuous drain current rating of 100mA. The component is RoHS compliant and lead-free.

Feature Summary

N-channel junction field-effect transistor construction
Depletion mode operation capability
Through-hole compatible TO-92 cylindrical packaging

Applications

Low-noise amplifier circuits
Constant current source implementations
Analog switching applications

Procurement Notes

Verify the manufacturer designation as Linear Integrated Systems, Inc., distinct from other entities using similar part numbers. Confirm the physical package is the standard TO-92 with three leads. Ensure the component meets RoHS environmental standards if required by the assembly process. Cross-reference the specific suffixes to confirm the absence of non-standard variations.

Selection Notes

Select this component for designs requiring an N-channel JFET in a low-profile through-hole package. Consider the 60V breakdown voltage and 100mA current limits when sizing the circuit. Evaluate the noise performance requirements against typical JFET specifications. Ensure the thermal management strategy accommodates the power dissipation capabilities of the TO-92 case.

Part Context

This component belongs to the category of discrete semiconductor transistors, specifically Junction FETs. It serves as a fundamental active element in analog signal processing. The TO-92 package provides a cost-effective solution for prototyping and high-volume consumer electronics where surface-mount space is not the primary constraint.
