The BU807TU bipolar junction transistor is a commonly used two-terminal device with a variety of applications in electronics. It is constructed in a TO-220 package and has a power dissipation rating of 2.5W

The BU807TU is used in many electronic applications due to its numerous advantages. Its very low collector-emitter saturation voltage, rapid switching speed, low operating power requirements and excellent temperature stability make it very useful in a large number of applications.

The BU807TU can be used as an amplifier in radio frequency (RF), audio, video and digital communications applications. It is widely used in voltage control oscillators, high frequency amplifiers, and medium power audio amplifiers. It can be used as a switch in DC relays, inverters and power supplies, and as a linear amplifier with feedback for frequency control in RF and IF stages.

The BU807TU is capable of operating at frequencies from 0.1 MHz to 1 MHz, and its good reverse current characteristics make it suitable for use in high gain amplifier circuits including cascode stages. It is also suitable for use in negative feedback amplifier designs.

The BU807TU can be used as an amplifier or phase-shifter in television circuits and can be used to drive large speaker systems. Its low noise figure is a definite advantage in these applications.

The BU807TU is a non-saturating transistor and its normal bias characteristics are ideal for use in linear D.C. circuits.

The working principle of the BU807TU can be explained in terms of the base-emitter junction and the base-collector junction. When the transistor is use in a circuit, it is biassed so that a small current flows from the base terminal to the emitter. This current causes a voltage to appear across the base-emitter junction. This causes current to flow from the emitter to the collector. As the collector current increases, the voltage across the base-emitter junction increases, and this causes a further increase in collector current. This increase in current is known as “feedback” and it is responsible for many of the advantages of the BU807TU.

With the correct biasing of the base terminal, the gain of the BU807TU can be controlled to achieve the desired output voltage or current levels. The gain of the transistor can be increased or decreased by adjusting the biasing voltage of the base terminal.

In summary, the BU807TU is a very useful single bipolar junction transistor with a wide variety of applications in electronics. Its low saturation voltage, rapid switching speeds and low operating current requirements make it suitable for use in amplifiers, switches, relays, inverters and other linear D.C. applications. Its gain can be controlled by correctly biasing the base terminal, and its low noise figure makes it suitable for use in audio, video and television applications. The working principle of the BU807TU can be explained in terms of the base-emitter and the base-collector junction.
