The BC846A is a small signal PNP transistor manufactured by Diotec. It is a general-purpose discrete device with an overarching goal of providing high-performance, cost-effective amplification. The transistor offers low noise figures, low voltage operation, and low power consumption, making it well-suited for many applications including audio pre-amplifiers, attenuators, data line switching, and motor-control circuitry. It features a maximum collector-emitter voltage of 45V, a breakdown voltage of 45V, and a maximum collector current of 600 mA. It has a low collector-emitter saturation voltage of 0.2 V and a good transition frequency of 200 MHz. The BC846A is available in a SOT-23-3 package, allowing it to be soldered to a circuit board directly.
