Three Applications for 2N2222 Transistors in Texas

Sharing is caring!

Bipolar junction transistors are used for a variety of applications in the world of electronics. One specific example of a bipolar junction transistor is the 2N2222 transistor. It is made from either silicon or germanium, can conduct low to medium currents, and can operate at high speeds. It is one of the most popular transistors on the market because of its low cost and small size. Three applications for 2N2222 transistors in Texas are for the amplification of a current, as an on/off switch, and for pulse-width modulation.

Amplification of a Current

One application for a 2N2222 transistor is for the amplification of a current. Current amplification occurs when the current from an input signal is collected along a circuit, and its magnitude is increased by a fixed multiple. Then the amplified current is relayed to the next circuit or to the end device. The 2N2222 transistor can handle higher current loads that other comparable transistors in its class, making it great for this job.

On/Off Switch

Another application for a 2N2222 transistor is as an on/off switch. By using it as an on/off switch, it effectively controls the power from one part of a circuit to another. The transistor’s specific job in this setting is to conduct current between a collector and an emitter, and it does so only when a voltage is applied to the base pin. When the voltage is applied and the transistor is conducting current, the switch is on. When no voltage is applied to the base pin and the transistor is not conducting current, the switch is off.

Pulse-Width Modulation

The third application for a 2N2222 transistor is for pulse-width modulation. This is a specific technique that is used often to control the amount of power that is delivered to a load. In addition, pulse-width modulation is used to control the speed of the motor for a DC motor and to help generate certain levels of analog voltage. Very little power loss is created when switching devices, making this technique popular and advantageous.
