Product details

The NXP BFU530XRR is an NPN silicon RF transistor in a SOT-143R surface-mount package, designed for low-noise amplifier stages in automotive and industrial wireless systems. Its 11 GHz transition frequency and 21 dB gain make it suitable for L-band and lower S-band applications, while the 0.65 dB noise figure at 900 MHz suits GPS, cellular, and ISM-band receiver front-ends. The AEC-Q101 qualification and -40°C to 150°C junction temperature range allow deployment in under-hood automotive modules and outdoor telecom enclosures.

SOT-143R is a four-lead surface-mount package with a collector pad that also serves as the thermal slug. The pinout — base, emitter, collector, ground — is standard for this footprint family. Solder pad layout per the datasheet recommendation keeps parasitic inductance low at UHF frequencies.

Frequently asked questions

Is BFU530XRR a replacement for BFU520XRR?

The BFU530XRR has a higher transition frequency (11 GHz vs the BFU520XRR's lower fT) and higher gain. It is not a direct pin-compatible replacement in all designs; verify the bias and matching network if substituting. For a drop-in with similar specs, compare the BFU530XRR against the BFU520XRR datasheet.

Is BFU530XRR RoHS compliant?

Yes, the BFU530XRR is ROHS3 compliant.

Is BFU530XRR suitable for 433 MHz applications?

Yes. With an 11 GHz fT and 21 dB gain, the BFU530XRR has ample bandwidth for 433 MHz ISM-band LNA or driver stages. The 0.65 dB noise figure at 900 MHz suggests even lower NF at 433 MHz, which benefits receiver sensitivity.
