The BFQ19S is an NPN silicon RF transistor designed for high-frequency amplification applications. Manufactured by Infineon, this transistor offers a collector-emitter breakdown voltage of 15V minimum and a DC current gain range of 70 to 140. With a transition frequency of 4 to 5.5 GHz, it is suitable for RF circuits up to the GHz range. The transistor features low leakage currents: collector-emitter cutoff current of 10µA maximum, collector-base cutoff current of 100nA maximum, and emitter-base cutoff current of 100nA maximum. Its collector-base capacitance is typically 1.05pF and collector-emitter capacitance is 0.4pF, making it suitable for high-frequency designs. The BFQ19S is commonly used in RF amplifier stages, oscillators, and other wireless communication circuits.
