How to use BC847 Transistor

BC847B Pinout

The BC847B is a widely used NPN bipolar junction transistor housed in a compact SOT-23 (TO-236) surface-mount package. It is ideal for general-purpose low-power switching and amplification. The correct identification of the transistor’s three pins—Base, Emitter, and Collector—is crucial for proper circuit integration and functionality.

With its reliable performance and small footprint, the BC847B is commonly found in consumer electronics, signal processing, and digital interfacing circuits. Understanding the pinout—Base on pin 1, Emitter on pin 2, and Collector on pin 3—ensures optimal performance and ease of design implementation.
