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
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
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
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:
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.
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.
