2N1479 is a type of bipolar junction transistor (BJT) that is commonly used for an array of different applications in the electronics industry. It is classified as a “single” BJT and can be used for audio amplification, signal processing, as well as a variety of other applications. In this article we will discuss the 2N1479 application field and its working principle in detail.

2N1479 is a single chip PNP transistors that allows current to flow between its three different terminals, known as the emitter, collector, and base. It mainly operates in the circuit request of an amplifier, where a current generated from the external signal applied to its base is amplified and passed through to the emitter.

The main application field of the 2N1479 transistor is signal and audio amplification. In this use, it is able to amplify both voltage and current signals, allowing for the transmission of audio over great distances. In addition, it can be used for digital audio amplification in devices such as smartphones, tablets, and computers to allow for higher-quality sound production.

It is also used in radio-frequency applications, as it can achieve operating frequency ranges from 50 GHz to 1 GHz, allowing for frequencies to be transmitted over a large distance. As a result, the 2N1479 transistor can be used for wireless telecommunications and satellite communications.

In addition, the 2N1479 transistor can be used for signal processing in circuit applications, such as a collector modulated amplifier. This type of amplifier modulates the signals of a waveform before they are sent further to the receiver.

To understand the working principle of the 2N1479 transistor, we will take a look at its component structure. As previously mentioned, the 2N1479 is a single chip PNP transistor which consists of three terminals: the emitter, collector, and base. The base is where the external signal is applied and the current is amplified and passed through to the emitter, where it is further transmitted. The collector is then responsible for collecting current from the emitter, which is sent out of the device once the amplification process is complete.

When a voltage is applied to the base terminal, it sets off a sequence of processes known as the “transistor action”. This action causes an increased current to flow through the collector terminal, while a decreased current is driven along the emitter. This amplification process is what allows signals to be amplified and transmitted over greater distances.

In summary, the 2N1479 is a single chip PNP transistor which is mainly used for signal amplification, radio-frequency applications, and signal processing applications. Its component structure consists of three terminals: the emitter, collector, and base. When a voltage is applied to the base terminal, the transistor action is initiated, allowing for increased current to flow through the collector terminal, while a decreased current is driven along the emitter.
