The BC547 is a popular NPN bipolar junction transistor (BJT) that is commonly used in electronic circuits. It is designed for general-purpose amplification and switching applications. The BC547 transistor has three leads: the emitter (E), base (B), and collector (C).

 

Here are some key specifications of the BC547 transistor:

 

Maximum Collector Current (Ic): 100 mA

Maximum Collector-Emitter Voltage (Vce): 45 V

Maximum Collector Power Dissipation (Pc): 500 mW

DC Current Gain (hfe): Typically around 100 to 800, depending on the specific model and conditions.

Transition Frequency (ft): Typically around 150 MHz.

The BC547 transistor is widely available and can be used in various applications, including amplifiers, signal processing circuits, and low-power switching circuits. It is often used in hobbyist projects and educational settings due to its affordability and ease of use.
