BC547 Transistor Basic Knowledge, Pinout and Application

What is BC547 Transistor

When asking BC547 belongs to which type of the triode, basically, we think that BC547 is a normal NPN (Negative-Positive-Negative) junction transistor. And he bc547 parameter and the bc547 pin diagram are very important in the basic knowledge of BC547.

Below I will discuss the new electronic component called BC547. It is a BJT transistor and is often used to satisfy the need of quick switching. If you use this transistor in an engineering project, I want to suggest you to download BC547 Proteus Simulation. As we all know, simulating before entering the hardware is always a better strategy. So just let us to take a look at the basic knowledge of BC547.

Basic Knowledge of BC547 Transistor Parameters

Followings are the key knowledge of BC547 that you must understand:

  • BC547 is a bipolar junction transistor (BJT).
  • It is kind of an NPN transistor.
  • It has three terminals: Emitter, Collector and Base.
  • The maximum current gain of BC547 is 800A.
  • The Collector−Emitter Voltage is 65V.
  • The Collector-Base Voltage is 80V.
  • The Emitter-Base voltage is 8V.

Operational Status of BC547 Transistor

BC547 has two operation status: forward bias and reverse bias.

In the status of the forward bias, the current can pass when the collector and emitter are connected.

While in the status of the reverse bias, it acts as a disconnect switch and current cannot pass.

BC547 Transistor Application

BC547 is usually used for current amplifier, quick switching and pulse-width modulation (PWM).

Therefore, if you need to control the speed of a motor or actuator in some of your projects, you can simply use this transistor to achieve it. In addition, it can also be used as a switch that you can easily switch on or off a DC device with this transistor.
