The BC547 NPN General Purpose Transistor 45V 100mA TO-92 Package Pack of 5 is a set of industry-standard TO-92 packaged NPN silicon planar epitaxial transistors designed for low-noise audio amplification and general-purpose signal switching applications. Operating with a collector-emitter voltage (V_CEO) of up to 45V and a maximum continuous collector current (I_C) of 100mA, these transistors are optimal for processing small, sensitive analog and digital signals.
Housed in a compact 3-pin TO-92 plastic package, the BC547 features exceptionally high current gain (h_FE) and low noise output, making it an ideal choice for preamplifier stages, active signal filtering, and sensor amplification.
These transistors are widely used for driving small loads, signal inversion, relay driver logic, audio pre-amps, and general switching networks. They plug easily into breadboards, stripboards, perfboards, and custom printed circuit boards (PCBs), making them fully compatible with 3.3V and 5V microcontrollers including Arduino, ESP32, Raspberry Pi, PIC, AVR, and DIY electronic prototyping.
