Then, it has a continuous Collector current (I C) of 100mA.Secondly, its DC Current Gain (h FE) is at a maximum of 800.That current needs to go somewhere, and therefore, it drains out of the emitter. The base controls the biasing of the transistor. Here, the current’s job is to flow through the collector pin. Wondering what the BC547 transistor’s pinout configuration is? Here is everything you need to know: We’ll discuss this in more detail later, but usually, you’ll place this type of transistor after a circuit’s load. When applying power to the control pin/ base terminal, the energy will flow from the collector to the emitter. What is a BC547 Transistor?Ī BC547 is a type of NPN. If you’re into electrics, you’ll already know that the flow of electrons makes this process work.Ī diagram of the BC547. These three sections are an emitter, base, and collector. What is an NPN Transistor?Īn NPN Transistor (or negative-positive-negative transistor) is a general-purpose transistor used for signal amplification.įurthermore, like most transistors, an NPN has three layers controlled by a collector current. For this reason, it is a common base amplifier. Why is that? The power between the emitter and collector can easily be higher than the base. Likewise, you may also be familiar with the terms transistor and amplifier in one sentence. Often, triggering the base current allows the emitter and collector to connect, thereby forming a switching element. In technical terms, we have the input as emitter, the output as a collector, and the control line as the base. In a nutshell, it is an electrically controlled switch.įor this specific switch to work, it requires input, output, and a control line. It is especially crucial if you’ll be working with driver modules, amplifier modules, or Darlington pairs. So, are you ready to learn more about these fascinating electronic components? Let’s get started! What Is A Transistor?īefore we jump into what a BC547 transistor is, let’s cover what a transistor is. The BC547 is a necessary transistor to know and understand as a switch or an amplifier.
