ONSemi MMBF170LT1G's Category-FETs, MOSFETs
Metal - Oxide - Semiconductor Field - Effect Transistors (MOSFETs for short) are a type of semiconductor commonly used in both digital and analog circuits, and they are also useful power devices. As an original compact transistor, MOSFETs are suitable for a wide range of electrical applications.
It has long been widely believed that many technological advancements in the 21st century would not have been possible without MOSFETs. MOSFETs are more widely used than Bipolar Junction Transistors (BJTs) because they require very little control current for the load current. The conductivity of an enhancement-mode MOSFET can be increased in the "normally off" state. The voltage applied through the gate can minimize the conductivity in the "normally on" state. The miniaturization process of MOSFETs is relatively simple, and they can be effectively reduced in size for compact applications.
Other advantages of MOSFETs include fast switching (especially for digital signals), minimum power consumption, and high-density capacitance, which make it an ideal choice for large-scale integration.
MOSFETs are the core components of integrated circuits. Thanks to their miniaturization, they can be designed and manufactured in a single chip. The MOSFETs on an integrated circuit chip are four - terminal elements, namely the source (S), the gate (G), the drain (D), and the body (B). The body is usually connected to the source, enabling the MOSFET to function as a field-effect transistor. There are mainly two types of transistors. One is the Bipolar Junction Transistor (BJT), and the other is the Field - Effect Transistor (FET). MOSFETs belong to the field-effect transistor type. BJTs are usually used for currents below 1 ampere; MOSFETs are typically used for applications with larger currents.
There are two types of MOSFETs: depletion - mode and enhancement - mode. The depletion-mode MOSFET works like a closed switch. A positive voltage generates an operating current, and a negative voltage stops the operating current. The enhancement mode MOSFET is a type commonly used in modern applications. As mentioned before, a MOSFET is a device used to switch or amplify electrical signals. These can be achieved by changing the conductivity, which can be changed by varying the applied voltage.
MOSFETs are the most commonly used transistors in digital circuits and can achieve million-level integration in memory chips or microprocessors. In addition, MOSFET transistors are commonly used as switches in voltage-controlled circuits. It is believed that the emergence of MOSFETs has contributed to the development of a series of technological devices, such as pocket calculators and digital wristwatches.
