Product Overview
The BC847 is an NPN bipolar junction transistor (BJT) designed for general-purpose switching and small-signal amplification. It features a 45V collector-emitter voltage rating, 100mA maximum collector current, and 250mW power dissipation. Its DC current gain and switching characteristics support low-current signal processing and discrete transistor circuits.
Housed in a compact SOT-23 surface-mount package, the BC847 is suitable for signal amplification, low-current switching, and transistor interface circuits. The BC847 family also offers A, B, and C gain selections for applications requiring more specific current gain characteristics. Its small package supports space-efficient PCB assembly.
