It is also commonly used in pulse circuits, timing circuits and as an analog switch. It can also be used to replace traditional discrete components, such as transistors and diodes.

Working Principle

The FMMTL718TA is a common-emitter, bipolar transistor. It works by amplifying an electrical signal. This is achieved when a small electrical current flows through the transistor’s base terminal and the current is amplified and then flows through the collector and emitter terminals. This amplifies the current, the change in current being related to the change in voltage at the base terminal. The transistor can then be used as a switch, amplifier, oscillator or even a voltage regulator.

As the voltage at the base increases, so does the current from the collector to the emitter, which causes the output current to increase. When the base voltage is low, the current from the collector to the emitter is reduced and the output current decreases. As the voltage at the base increases further, the current from the collector to the emitter reverses and the transistor is said to be in saturation. This occurs when the voltage at the base is greater than the voltage at the emitter.

The FMMTL718TA has a very high current gain, typically in excess of 500, making it ideal for switching applications. It also has a low saturation voltage, meaning that it can operate with a very low voltage difference between the collector and emitter without adversely affecting the current flow. This makes it ideal for use in low voltage circuits.
