PN4393 TO-92 3L ROHS

Overview

The PN4393 is a small signal field-effect transistor manufactured by Linear Integrated Systems, Inc. It is an N-channel silicon junction FET housed in a TO-92 cylindrical plastic package. The device operates in depletion mode and contains one element with three terminals. Key electrical parameters include a maximum drain-source on-resistance of 100 Ω and a maximum feedback capacitance (Crss) of 3.5 pF. The component is lead-free and RoHS compliant.

Feature Summary

• N-channel silicon junction technology
• Depletion mode operation
• TO-92 through-hole packaging

Applications

Procurement Notes

Verify the manufacturer designation carefully, as official documentation lists Rochester Electronics as the supplier for this part number. Confirm that the specific unit matches the TO-92 cylindrical package and depletion mode characteristics. Ensure compliance requirements align with the lead-free and RoHS status documented in the component specifications.

Selection Notes

Select this component for low-power analog switching or amplification applications requiring N-channel JFET characteristics. The TO-92 package limits current handling capabilities compared to surface-mount or larger packages. Verify that the 100 Ω on-resistance and 3.5 pF feedback capacitance meet the specific circuit impedance and frequency response requirements.

Part Context

This component belongs to the category of small signal field-effect transistors. It is classified under discrete semiconductor transistors. The TO-92 package is a standard through-hole form factor commonly used for low-power general-purpose electronic components.
