BFG310W/XR,115

Overview

The BFG310W/XR,115 is an NPN silicon planar epitaxial transistor housed in a 4-pin SOT343R (CMPAK-4) plastic package. It operates as a wideband RF device with a transition frequency of 14 GHz and a maximum collector-emitter voltage of 6 V. The component supports a DC collector current of 10 mA and total power dissipation of 60 mW at a solder point temperature up to 145 °C. Key electrical characteristics include a minimum DC current gain of 60, a typical noise figure of 1 dB at 2 GHz, and a maximum stable gain of 18 dB at 1.8 GHz.

Feature Summary

• High power gain suitable for RF amplification
• Low noise figure for signal integrity
• High transition frequency for broadband operation
• Gold metallization for enhanced reliability

Applications

• Radio Frequency front end applications in the GHz range
• Analog and digital cellular telephones

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status and check for specific manufacturing origin markings on the package. Ensure storage conditions meet specified limits to maintain junction integrity before assembly.

Selection Notes

Select this component for designs requiring high-frequency performance within a low-voltage constraint. Verify that the application circuit can maintain the collector-emitter voltage below 6 V and keep power dissipation under 60 mW. Ensure thermal management allows the solder point temperature to remain within the specified operating range.
