BC546 Specs and Replacement

The BC546 is an NPN bipolar junction transistor widely used for low-noise, general-purpose amplification and switching. It features a maximum collector-emitter voltage of 80V and a continuous collector current of 100mA. With its high gain (typically 110-800) and low leakage, the BC546 performs well in audio stages, sensor interfaces, digital control circuits. Its TO92 package ensures easy PCB integration, while its robustness and predictable characteristics make it a reliable choice for hobbyist and industrial designs.
