BC548 NPN Transistor

The BC548 NPN Transistor shares the same general-purpose reliability as its BC547 sibling, tuned instead for slightly lower current applications, making it well suited to smaller relay drivers, LED circuits, and signal amplification tasks. It remains a familiar, easy-to-source component for anyone building switching or amplifying circuits.

With a continuous collector current of 100mA and a maximum current gain of 800, the BC548 handles light switching duties efficiently while keeping power dissipation low. Its 30V collector-emitter rating suits most low-voltage hobbyist and educational projects, and the compact TO-92 package makes it simple to mount on breadboards or solder directly onto a finished PCB.

• General purpose NPN transistor – reliable switching and amplification
• Continuous collector current – 100mA
• Collector-emitter voltage – rated up to 30V
• Current gain – up to 800 (max)
• TO-92 package – breadboard and PCB compatible
• Common applications – relay drivers, LED drivers, small amplifiers
