Product Description

The BC846B is an NPN Transistor designed for general-purpose amplification and switching applications in compact SMD circuits. Housed in a space-efficient SMD Transistor package (SOT-23), it supports a collector-emitter voltage of up to 65V and a collector current of 100mA, with a peak current rating of 500mA. Its DC current gain (hFE) ranges from 200 to 450, ensuring reliable signal amplification. Operating within a temperature range of -55°C to 150°C, this transistor is widely used in industrial automation, consumer electronics, and communication systems for its fast switching speed and low saturation voltage. Key advantages include its small footprint, compatibility with high-density PCB designs, and robustness in harsh environments. However, it is not suitable for high-power applications due to its limited current handling capacity. The BC846B lacks built-in protection features, requiring external circuitry for overvoltage or overcurrent scenarios.
