Description

BFR380F is a small-signal RF transistor (part of the BFR family) used for high-frequency amplification. It’s typically employed in RF front ends, such as VHF/UHF amplifiers, mixers, and preamps, where a high transition frequency (ft) and low noise are advantageous. The exact electricals (Vce, Ic, hFE, ft, package type) depend on the specific manufacturer and datasheet, so you’ll see variants in SMD packages (e.g., SOT-23 or similar).
Key points:
- Use: RF amplification and switching in RF front-ends.
- Package: varies by vendor; check the exact datasheet for pinout and mechanical data.
- Typical specs to verify: operating voltage/current, gain, ft, noise figure, and power dissipation.
- Biasing: usually biased in common-emitter or common-base configurations with appropriate base drive and emitter degeneration as needed.
If you provide the manufacturer or a link to the datasheet, I can give a concise spec summary and a recommended schematic for the device.

Package

BFR380F comes in a 3-lead SOT-23 surface-mount package (SOT-23-3).

Pinout

- Pin count: 3
- Function: NPN RF transistor (SMD) for high-frequency amplification (used as RF amplifier in common-emitter configurations).

Manufacturer

Manufacturer: Infineon Technologies AG.
What kind of company: A German multinational semiconductor manufacturer and system-solutions company, producing ICs, discrete semiconductors, power devices, sensors, and related technologies for automotive, industrial, and consumer electronics.

Application

Applications: RF front-end in wireless communications (VHF/UHF), including preamplifiers, buffers, mixer/oscillator stages, detectors, and RF switches. Suitable for SOT-23, small-signal, high-frequency operation up to several hundred MHz (and into the low GHz in some designs).
