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.
Gain and noise figure — what they mean for the receiver chain
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.
Sourcing and lifecycle
The BFU530R carries an Active lifecycle status — no last-time-buy notice, no NRND flag. ROHS3 compliance covers the EU RoHS exemption set.
