FET,Field effect transistor,field effect transistor,unipolar transistor

Field effect transistor referred to as field effect transistor, by the majority of carriers involved in conduction, also known as unipolar transistor, belongs to the voltage-controlled semiconductor devices, then what are the characteristics of FET? Let's take a look.

With the advantages of high input resistance, low noise, low power consumption, large dynamic range, easy integration, no secondary breakdown, and wide safe working area, FET has become a strong competitor of bipolar transistors and power transistors.

FET features the following six points:

First, the FET is a voltage control device, which after VGS (gate voltage) grasps the ID (drain DC);

Second, the FET output DC is small, so its output resistance is very large.

Third, it is the application of minority carrier thermal conductivity, so its measurement of stability is better;

Fourth, it consists of narrowing the path of the small electrical coefficient of contraction is smaller than the transistor composed of a narrow path of electrical small coefficient;

Fifth, the strong anti-radiation effect of FET;

Sixth, because there are no miscellaneous activities scattered particles are caused by young children, because of low noise.

Lu Jing semiconductor production of electronic components complete model, many parameters. Lu Jing has a reliable quality management system, the products sold are genuine original (original original packaging), samples can be tested first, and product specifications can be downloaded from the official website.

MOS管有啥难的？

三极管中参与导电的有两种极性的载流子，所以也称为双极型三极管。本文介绍另一种三极管，这种三极管只有一种载流子参与导电，所以也称为单极型三极管，因为这种管子是利用电场效应控制电流的，所以也叫场效应三极管(FET)，简称场效应管。MOS在电路中应用很常见，主要作为开关管，在电机驱动电路中常见。

MOS’s Definition and Classification

The bipolar transistor amplifies the small changes in the input current and outputs a large current change at the output. The gain of a bipolar transistor is defined as the ratio of the input to the input current (beta). Another type of transistor, called a field effect transistor (FET), which translates the change in input voltage into a change in output current. The gain of the FET is equal to its trans-conductance, defined as the ratio of the change in output current to the change in input voltage.

What Are the Characteristics of Field Effect Transistors?

Field effect transistor (is an electronic component that controls the current through the electric field effect. It depends on the electric field to control the shape of the conductive channel, and therefore can control the conductivity of the channel of a certain type of carrier in the semiconductor material. Then the characteristics of the field effect transistor What are we going to? Let‘s find out.

通俗易懂讲解MOS管

MOS管的英文全称叫MOSFET(Metal Oxide Semiconductor Field Effect Transistor)，即金属氧化物半导体型场效应管，属于场效应管中的绝缘栅型。因此，MOS管有时被称为绝缘栅场效应管。在一般电子电路中，MOS管通常被用于放大电路或开关电路。

These Kinds of MOS Tubes “Breakdown“, How Many Do You Know?

The electric field in the depleted layer is accelerated to reach the drain end. Therefore, the current through the breakdown also has a sharp increase point. The sharp increase of this current is different from the sharp increase in the avalanche breakdown. The current at this time is equivalent to the source substrate. The current of the PN junction is guided by the current, and the current when the avalanche is broken is mainly the avalanche current when the PN junction is reversely broken. If no current is limited, the current of the avalanche breakdown is large.

场效应管的工作原理及制造工艺

场效应管(FET)是场效应晶体管(field-effect transistor)的简称，它是一种通过电场效应控制电流的电子元件。它依靠电场去控制导电沟道形状，因此能控制半导体材料中某种类型载流子的沟道的导电性。场效应管不但具有双极性晶体管体积小、重量轻、寿命长等优点，而且噪声低，热稳定性好，抗辐射能力强，使之广泛地应用于各种电子电路之中。
