Field effect transistor referred to as field effect transistor, by the majority of carriers involved in conduction, also known as unipolar transistor, which 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) to grasp the ID (drain DC);

Second, the FET output DC 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 narrow path of electrical small coefficient;

Fifth, the strong anti-radiation effect of FET;

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

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