Looking for the right transistor for a project? Finding the right transistor starts with understanding transistors, how they work in electronic components, and some of the basic differences between the main transistor types. The 2N2222 is a very popular transistor that works in many applications, but it is not always the right transistor for the job. Read on to find out more about transistors and how to find 2N2222 transistors in Florida.
How Do Transistors Work?
Transistors are small electronic components that were developed in the middle of the last century to replace vacuum tubes in many electronic devices. They are constructed of three layers of semiconductor material. This material allows for the conduction of electricity but, because it is less conductive than a true conductor like metal, it can also be used to impede or amplify current control depending on the project needs.
Two Main Types of Transistors
Transistors can be broken down into two broad categories: PNP transistors and NPN transistors. The P stands for positive and the N stands for negative, and the designations refer to whether the semiconductor used in a particular layer is considered positively charged or negatively charged. In PNP transistors, two positive layers sandwich a negative layer. In NPN transistors, two negative layers sandwich a positive layer. Neither configuration is superior, but their configuration does impact how they interact with other electronic components, which makes it important to get the correct configuration.
2N2222 Transistors
The 2n2222 transistor is one of the most common transistor types and is used in a variety of applications. It is a good choice when a project requires a small-signal transistor. However, it is important to compare project specs and part specs to optimize a project. Other transistors that may also work in projects requiring a 2N2222 include the BC548, the 2N2907, the 2N3904, the 2N3904, and the 2N2219.
