Working on an electronics project? If so, then transistors are probably included in the build components. After all, transistors are a part of almost all modern electronics. While there are many different types of transistors available, one of the most commonly used is the 2N2222. This workhorse of a transistor can be used in a variety of different projects and across an array of current, voltage, and amp requirements. Read on to find out more about finding 2N2222 transistors in Pittsburgh.
What Are Transistors?
While electricity has been around for well over a century, the advent of the transistor helped usher in the age of modern electronics. Transistors replaced vacuum tubes in electronics because transistors are much smaller than vacuum tubes. Transistors consist of three layers of semiconductor material on a small surface. Working together, these layers can not only conduct electricity but also act as a switch to turn off current and a dial to increase or decrease the current.
Why Are Transistors Used in Electronics?
Transistors are used to impact power. Their most basic function is to act as a switch and turn the power on or off as required. However, they can also amplify or decrease power, making them more nuanced than a basic switch. While their versatility contributes to their use in electronics, it is not the only reason for their popularity. They are also very affordable and much smaller than vacuum components, which has led to incredible decreases in the space needed for modern electronics.
What Is the 2N2222 Transistor?
The 2N2222 transistor is an NPN bipolar junction transistor designed to handle medium voltage, low power, medium current applications at speeds approaching high-speed. The versatility of the 2N2222 makes it a favorite choice for many projects, though it may not always be the best choice. Similar transistors with slightly different JEDEC specifications, which may be better suited for a particular application, include the BC548, the 2N2907, the 2N3904, and the 2N2219.
