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. Are you interested in learning more about the topic? You’ve come to the right place!
