BC547 NPN Transistor – 3 Pieces

The BC547 is a general-purpose NPN bipolar junction transistor designed for low-power amplification and switching applications. It supports a maximum collector current of 100 mA and a collector-emitter voltage of 45 V, making it suitable for signal processing and control circuits. Commonly used in audio preamplifiers, sensor interfaces, and logic-level switching, it features stable DC gain and low noise characteristics. The device is compatible with standard through-hole PCB designs and operates reliably over a wide temperature range of –55 °C to +150 °C.
