Of all the transistors on the market today, the 2N2222 is one of the most popular and widely used. The following is a brief description of how 2N2222 transistors in New Jersey are made and what they do.
A transistor is a
device that controls the flow of electricity, acting as either a
switch or an amplifier. The first transistor was invented by Bell
Labs in 1947 when scientists added impurities to the element
germanium, weakening it and making it a semiconductor. All
transistors are made of semiconductor materials that allow the
precise control of electrical conductivity.
How Was The
transistor was developed by Motorola and launched in 1962. Though the
company had been making transistors for some years, a scientist named
Jack Haenichen developed the annular process that allowed transistors
to have a higher voltage output. This process led to the development
of the 2N2222, which was first manufactured inside a metal can known
as a TO-18.
What Is The
Structure Of The 2N2222?
The 2N2222 is a
type of NPN bipolar junction transistor, and it consists of three
layers of semiconductor material. Though the first transistors were
made of germanium, modern ones are typically made of silicon, which
is also a semiconductor. The middle layer, known as the base, is
positively charged (P doped), while the two outer layers, known as
the collector and the emitter, are negatively charged (N-doped).
How Does A
The 2N2222 is a
current-controlled transistor. This means that the output of the
transistor depends on the current that flows into the base. If a
small amount of current is input into the base layer, a large amount
of current will flow between the collector and emitter. This type of
transistor can be used as either a switch or an amplifier.
What Are Some
2N2222 transistors in New Jersey are used in a wide variety of applications. For one thing, as mentioned above, they can be used to amplify current. They can also be used as an automatic on/off switch inside an appliance. Another common application is pulse width modification. Visit Cornerstone Components to learn more.
