What kind of transistor is bc547? We basically think that BC547 is an ordinary NPN junction transistor; and the bc547 parameter and bc547 pin diagram are more important in the basic knowledge of BC547.

Below I will discuss the new electronic component called BC547. It is a BJT transistor, usually used where fast switching is required. If you use this transistor in an engineering project, then I suggest you download Proteus Simulation of BC547, because it is always a better strategy to simulate before entering the hardware. So let's take a look at the basics of BC547. This is the pinout diagram of BC547:

Basic knowledge of BC547 of bc547 parameters

The following are the key points of BC547 that you must know:

BC547 is a bipolar junction transistor, abbreviated as BJT.

It is an NPN transistor.

Its three terminals are:

Emitter

Collector

Base

The maximum current gain of BCli is 800A.

The collector-emitter voltage is 65V.

The collector-base voltage is 80V.

The emitter-base voltage is 8V.

BC547 working status

BC547 has two working states:

Forward bias.

Reverse bias.

In the forward biased state, the collector and emitter are connected, allowing current to pass. When in the reverse bias state, it acts as a disconnect switch and does not allow current to pass.

Application of BC547

BC547 is usually used for:

Current amplification.

Switch quickly.

Pulse width modulation.

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