BFU910F

BFU910F is a small-signal NPN transistor intended for high-frequency/RF use. It belongs to the BFU family of SMD transistors; the F suffix typically denotes RoHS-compliant, Pb-free status (verify with the vendor). It is used as a gain device in RF front-ends such as preamps, mixers, oscillators, and detector stages. Typical configuration is common-emitter with RF input at the base, collector load to Vcc, and emitter at ground; input/output impedance matching networks are needed for best noise and gain performance. Key specs to check in the datasheet include Vceo, Ic, total power, transition frequency (ft), current gain (hFE) at RF bias, noise figure, and package type. Because variants differ, always consult the exact datasheet for your supplier. If you share the manufacturer or a datasheet link, I can summarize the exact figures.

I can’t reliably list equivalents without the BFU910F’s package and key specs (polarity, frequency band, Vce/Ic, gain, power dissipation). Please provide a datasheet link or those parameters and I’ll give a short list of matching replacements (manufacturers and part numbers).

- Pin count: 3 pins (SOT-23 package).
- Pin functions (SOT-23 pin numbering): Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector (collector also tied to the package lead/frame).
- Device function: BFU910F is an NPN SiGe RF transistor intended for low-noise, high-frequency amplification and signal processing in VHF/UHF front-ends (low-noise amplifiers, gain stages, mixers, etc.).

Manufacturer: Nexperia (originally marketed under Philips/NXP).
What kind of company: Nexperia is a Netherlands‑headquartered semiconductor company that specializes in high‑volume standard products—discrete semiconductors, MOSFETs, analog and logic ICs—used in automotive, industrial and consumer electronics. It was formed when the standard products business was spun out of NXP.

BFU910F is a high-frequency NPN transistor (SMD) used for RF amplification and switching. Typical applications include:
- VHF/UHF RF amplifiers and preamplifiers
- Mixer, oscillator, and front-end stages in receivers and transceivers
- Broadband RF gain blocks in telecom and wireless equipment
- RF buffers and switching networks in compact RF/microwave modules
Note: Always verify exact device specs (fT, gain, max voltage/current) from the manufacturer datasheet for your design.

Do you mean the BFU910F RF transistor from Nexperia/Infineon? I can look up the exact datasheet and give the precise package type — shall I fetch that now?
