Product details

RF front-end LNA transistor for automotive and industrial bands

Rated for a -40°C to 150°C junction temperature range and qualified to AEC-Q101, this part handles under-hood automotive environments and industrial high-temp enclosures without derating the collector current up to 40 mA. The 450 mW power dissipation limit is sized for a Class-A LNA bias point; keep the board copper pour adequate for the SOT-143B footprint to stay within the thermal envelope at 150°C ambient.

The 60 minimum DC current gain at 10 mA, 8 V confirms the DC beta is adequate for bias stability, though the RF designer will set the collector current via the emitter degeneration resistor, not the beta — standard practice for this class of NPN RF transistor.

ROHS3 compliance covers the EU RoHS exemption set.

Frequently asked questions

What is BFU530R's gain and noise figure?

BFU530R delivers 21.5 dB gain with a 0.6 dB noise figure at 900 MHz, and has an 11 GHz transition frequency. This combination suits low-noise front-end stages in 900 MHz ISM-band and 2.4 GHz receivers.

What is the temperature grade of BFU530R?

BFU530R is rated for -40°C to 150°C junction temperature and carries AEC-Q101 automotive qualification, making it suitable for under-hood automotive and industrial high-temperature environments.

What is the closest pin-compatible alternative to BFU530R?

No official pin-compatible second source or cross-reference is listed in the manufacturer documentation for BFU530R. For a dual-source requirement, evaluate NXP's own BFU5xx family siblings in SOT-143B — the pinout is shared across the series, but gain and noise figure differ per variant.
