The 2N5664 is a single-transistor bipolar junction transistor (BJT). It is the smallest of the two-electrode devices and therefore has many applications in electronics.

The 2N5664 is a N-channel BJT used mainly in small signal amplifiers, amplifying current as well as for switching applications. The voltages at which the 2N5664 will operate depend on the current applied.

The 2N5664 has a maximum collector-emitter voltage of 8.0V, a typical gain bandwidth of 5.3 MHz and a maximum power dissipation of 1.6 Watts. In other words, it can amplify a signal over a frequency range of 5.3 MHz and gives an output voltage of up to 8.0V when it is driven by a small current.

The working principle of the 2N5664 is quite simple. The two terminal base and emitter are connected together and they act as the two main electrodes in the transistor. The collector is then connected to the base and emitter. When current is applied to the base, it also flows through the emitter and collector. This forms a closed loop current path which amplifies the current applied to the base.

The 2N5664 is a versatile transistor and can be used in a variety of applications, ranging from audio amplifiers to power switching devices. It can also be used as an oscillator, as in some high frequency oscillators.

In addition, the 2N5664 can be used in high voltage circuits. For example, it can be used in circuits for voltage and frequency conversion as it can handle high voltages.

In power switching applications, the 2N5664 can be used to switch high voltages, such as those used in power supplies and industrial equipment. It is also useful for controlling relays and motors as it can switch a large current.

The 2N5664 is also used in amplifiers to improve their performance in terms of frequency response and signal to noise ratio. This is done by using the transistor as a variable gain element in the input stage of the amplifier.

Finally, the 2N5664 can be used for audio applications, including power amplifiers and subwoofers. It can also be used for signal conditioning in speaker systems.

In summary, the 2N5664 is a single-transistor bipolar junction transistor (BJT) whose main applications are small signal amplifiers, amplifying current, and for switching and high voltage applications. It has a maximum collector-emitter voltage of 8.0V and a typical gain bandwidth of 5.3 MHz. Its working principle is based on current flow through the two main electrodes, the base and emitter, and the collector is connected to the base and emitter to form a closed loop current path. The 2N5664 is a versatile transistor with many applications in both audio and power electronics.
