All transistors function in the same general way, with a current that is applied to the inputs controlling the power output of another set of terminals. Some types of transistors have proved to be more versatile and useful than others, with certain designs becoming nearly ubiquitous over time.
Sales of 2N2222 transistors in Texas, for instance, have been going strong for decades and will almost certainly keep doing so. Transistors based on the proven 2N2222 design are used in many kinds of products.
A Transistor That Crops Up in Many Places
Some types of electronic circuits and products that include them give rise to very particular, unusual requirements. Many more are less demanding of the components that they include and can accommodate a wider variety of parts.
One of the most important reasons for the longtime popularity of 2N2222 transistors in Texas is that the design is simply so flexible. Far from being confined to a handful of specialized applications, it is appropriate to a huge range of possible circuits.
That fact has helped make the 2N2222 transistor one of the best-selling electronic components of all time. Today, it is frequently found in the circuits that enable the functionality of:
- Amplifiers – One of the most fundamental applications for almost any kind of transistor is the amplification of a signal. When solid-state transistors were first introduced, they were positioned as replacements for fragile, power-amplifying vacuum tubes. Electronic amplifiers are found in many places today, from compact smartphones to large public address systems. Circuit designers tasked with creating amplifiers quite often name 2N2222 transistors to do much of the heavy lifting.
- Power supplies – Many electronic circuits can run only on direct current (DC) but are expected to draw their power from household or commercial outlets. The conversion of alternating current that comes from such sources into DC can be accomplished by any of a number of means. Switching power supplies that incorporate 2N2222 transistors are frequently found handling such duties.
