PN4393 TRA

Overview

The PN4393 is an N-channel silicon Junction Field-Effect Transistor (JFET) manufactured by Central Semiconductor Corp. It features a TO-92 package with Drain, Source, and Gate leads. Key electrical parameters include a maximum Gate-Drain Voltage of 40 V, a maximum Gate-Source Voltage of 40 V, and a Power Dissipation rating of 625 mW at 25°C ambient temperature. The device operates within a junction temperature range of -65 to +150 °C. Electrical characteristics specify a Drain-Source Saturation Current (IDSS) ranging from 5.0 mA to 30 mA at VDS=20V, and a Gate-Source Cutoff Voltage (VGS(OFF)) between 0.5 V and 3.0 V.

Feature Summary

Designed for analog switching and chopper applications
N-channel silicon construction
Low gate leakage current
Hermetically sealed TO-92 case option available

Applications

Analog switches
Chopper circuits
Commutator designs

Procurement Notes

Verify the specific ordering suffix when purchasing. The TRA designation indicates a Tape and Reel packaging format. Confirm plating requirements; add PBFREE or TIN/LEAD suffixes if non-standard finishes are required. Ensure the supplier provides the official datasheet to validate the exact binning and electrical limits for the requested quantity.

Selection Notes

Select this component based on its low cutoff voltage and high input impedance suitable for precision analog signal routing. Compare IDSS ranges against circuit requirements to ensure proper biasing. Verify thermal management capabilities given the 625 mW dissipation limit in the TO-92 package. Consider the operating temperature range for extreme environment deployments.

Part Context

This part belongs to the PN4391 series of N-channel JFETs from Central Semiconductor. The series includes variants with different saturation current and cutoff voltage specifications to accommodate various analog design needs while maintaining consistent maximum ratings and package geometry.
