NE68039R-T1

Overview

The NE68039R-T1 is an NPN epitaxial silicon high-frequency transistor from the CEL NE680 series, housed in a surface-mount SOT-143R package. It features a gain bandwidth product (fT) of 10 GHz at VCE = 6 V and IC = 10 mA. The device exhibits a noise figure of 2.5 dB at 4 GHz under VCE = 6 V and IC = 5 mA conditions. Maximum available gain reaches 8.7 dB at 4 GHz with VCE = 6 V and IC = 10 mA. Absolute maximum ratings include a collector-to-base voltage of 20 V, collector-to-emitter voltage of 10 V, and a continuous collector current limit of 35 mA.

Feature Summary

• Designed for low noise and high gain applications up to 6 GHz
• Capable of operation at extremely low voltages and currents down to 0.5 V / 0.5 mA
• Available in multiple low-cost plastic surface mount package styles

Applications

• Low noise amplifier stages in RF circuits
• High frequency signal processing components
• Low voltage/low current amplifier designs

Procurement Notes

Verify component authenticity by cross-referencing the part number against official California Eastern Laboratories documentation. Confirm that the specific suffix corresponds to the SOT-143R package style. Ensure compliance with datasheet absolute maximum ratings during handling and integration to prevent permanent damage.

Selection Notes

Select this component for designs requiring high fT and low noise figures in compact surface-mount layouts. Compare performance metrics against the NE68039 variant if standard SOT-143 packaging is acceptable. Consider thermal resistance values when determining heat dissipation requirements for the specific PCB layout.
