Product Overview
The BC846 is an NPN bipolar junction transistor (BJT) designed for general-purpose switching and small-signal amplification. It features a 65V collector-emitter voltage rating, 100mA maximum collector current, and 250mW power dissipation. Its higher voltage rating compared with common 45V small-signal transistors supports low-current signal circuits requiring additional voltage capability.
Packaged in a compact SOT-23 surface-mount package, the BC846 is suitable for signal amplification, transistor switching, and discrete control interfaces. The BC846 series includes A and B current gain selections for different circuit requirements. Its small package supports space-efficient PCB assembly in low-power electronic circuits.
