FMMTL720TC transistors are one of the most popular category within bipolar junction transistors (BJT) as well as single devices. They are considered as popular components with fast-switching capability and reliability. In general, FMMTL720TC\'s are used mainly in three application fields - switching, amplification, and high-power motor control.

Switching Applications

FMMTL720TC transistors are used in switching applications to turn the current flow on and off rapidly to ensure high performance. These transistors are ideal for supplying intermittent high-power currents and controlling the flow of larger power between two parts. Some of the most common switching applications are circuit breaker control, fan motor control, solenoid control and lamp control.

Amplification Applications

The main advantage of using FMMTL720TC transistors for amplifying signals is its ability to quickly switch between the two states of on and off. This rapid switching ability allows for amplification of input signals without distortion. Common applications for amplification include audio amplifiers, radio transmitters and receivers, and instrumentation amplifiers.

High-power Motor Control Applications

FMMTL720TC transistors are known to have excellent thermal stability and high current-carrying capability. This makes them ideal for use in high-power motor control applications, such as controlling the speed of a DC motor or controlling a stepper motor. The transistors are also suitable for controlling larger AC motors, such as those used in robotics or industrial machinery.

Working Principle

The FMMTL720TC transistors operate on the principle of bipolar junction transistors (BJT). It consists of three different terminals, namely base, collector and emitter. The base terminal consists of two regions. One region is formed by diffusing lightly-doped p-type material into a heavily-doped n-type semiconductor substrate. The other region is formed by diffusing heavily-doped n-type material into a lightly-doped p-type semiconductor substrate. The emitter and collector terminals are separated by an insulating layer that serves to prevent direct current flow between the two regions.

In operation, the base terminal controls the current flow between the emitter and collector. By varying the current in the base terminal, the amount of current flowing between emitter and collector can be controlled. When a positive voltage is applied to the base terminal, the transistor is said to be in forward-active region, and the current flow between emitter and collector increases. When the voltage drops below the cut-off voltage, the transistor is said to be in reverse-active region, and the current flow between emitter and collector decreases.

To switch between the on and off states, a transistor is connected to an appropriate external circuitry, such as resistors and capacitors. By making use of the principle of capacitance, the transistor can be quickly switched between the on and off states, resulting in rapid and reliable performance.

Conclusion

FMMTL720TC transistors are one of the most popular transistors used in BJT and single applications, due to their fast switching capability and reliability. They are commonly used in switching, amplification and high-power motor control applications. The working principle of FMMTL720TC is based on the principle of a bipolar junction transistor, which allows for fast and reliable switching of the current flow between the emitter and collector.
