Its 5 GHz transition frequency (fT) means the usable gain extends past 2 GHz before roll-off becomes significant — enough for 900 MHz ISM-band, 1.8 GHz GSM, or 2.4 GHz WLAN LNA and driver stages. Gain spans 8.5 dB to 13 dB across the bias range, and the noise figure runs 1.8 dB to 3 dB at 900 MHz to 1.8 GHz. That NF floor is competitive for a general-purpose RF transistor — it keeps the receiver's cascaded noise figure low enough for most commercial radio front-ends without resorting to a dedicated low-noise SiGe part. ## DC bias headroom and thermal budget Collector-emitter breakdown is 15 V, and maximum continuous collector current is 210 mA — enough headroom for a typical LNA biased at 5–8 V and 10–50 mA, with margin for supply ripple or transient overshoot. Power dissipation is rated at 700 mW maximum. In a SOT-23-3 on a standard FR4 board with minimal copper, the junction-to-ambient thermal resistance is typically 250–300 °C/W — at 700 mW the junction would hit 175–210 °C above ambient, exceeding the 150 °C TJ max. Real designs should derate to 300–400 mW for reliable operation in a 25 °C ambient, or use larger copper pads to spread heat.","metaTitle":"BFR106E6327HTSA1 NPN RF Transistor, 15V 5GHz SOT-23-3","metaDescription":"Infineon BFR106E6327HTSA1 NPN RF transistor, 15V Vceo, 5GHz fT, 8.5-13dB gain, 1.8-3dB NF.
