2N4393UB/TR

Jfets Overview

The 2N4393UB/TR is a silicon NPN small-signal bipolar junction transistor manufactured by Microchip Technology. It utilizes an LCC-3 surface-mount package designed for automated assembly processes. The device supports a maximum collector-emitter voltage of 40 V and a collector-base voltage of 75 V, with an emitter-base breakdown rating of 5 V. It handles a continuous DC collector current of 1.5 A and dissipates up to 1 W of power. The component operates within a temperature range of -65 °C to +200 °C, featuring a minimum DC current gain of 20 at 1 A and a maximum of 150 at 500 mA.

Jfets Feature Summary

Jfets Procurement Notes

Verify the specific suffix configuration against official Microchip documentation to ensure compatibility with required manufacturing standards. Confirm that the LCC-3 footprint matches the target PCB design constraints. Validate RoHS compliance status directly from the manufacturer's datasheet prior to integration into regulated assemblies.

Jfets Selection Notes

Select this component when high current handling and wide operating temperature ranges are critical. Ensure the application circuit limits the collector current below 1.5 A to maintain safe operating area boundaries. Verify that the chosen heat dissipation strategy accommodates the 1 W power rating under worst-case thermal conditions.

Jfets Part Context

This part belongs to Microchip's legacy discrete semiconductor portfolio, often serving as a replacement for older military-grade specifications. The UB suffix typically denotes a specific tape-and-reel packaging format intended for high-volume surface-mount production lines.

Jfets Replacement Considerations

Consult official substitution guides for equivalent NPN transistors with matching LCC-3 footprints. Verify that alternative devices meet the same 40 V collector-emitter voltage and 1.5 A current requirements.
