Understanding the function and structure of MOSFETs
If the transistor can be called the greatest invention of the 20th century, then there is no doubt that the MOSFET in which a great deal of credit. 1925, on the basic principles of MOSFET patents published in 1959, Bell Labs invented th...Read more -
About the working principle of power MOSFET
There are many variations of circuit symbols commonly used for MOSFETs. The most common design is a straight line representing the channel, two lines perpendicular to the channel representing the source and drain, and a shorter line par...Read more -
Main parameters of MOSFETs and comparison with triodes
Field Effect Transistor abbreviated as MOSFET.There are two main types: junction field effect tubes and metal-oxide semiconductor field effect tubes. The MOSFET is also known as a unipolar transistor with a majority of carriers involved...Read more -

What are the application scenarios for MOSFETs?
MOSFETs are widely used in analog and digital circuits and are closely related to our lives.The advantages of MOSFETs are: the drive circuit is relatively simple.MOSFETs require much less drive current than BJTs, and can usually be driv...Read more -
The three main roles of MOSFETs
MOSFET commonly used three major roles are amplification circuits, constant current output and switching conduction. 1, amplification circuit MOSFET has a high input impedance, low noise and other characteristics, therefore, it is usu...Read more -
How to choose a MOSFET?
There are two types of MOSFETs, N-channel and P-channel. In power systems, MOSFETs can be considered as electrical switches. The switch of an N-channel MOSFET conducts when a positive voltage is added between the gate and the source. Wh...Read more -
Small Package MOSFETs
When the MOSFET is connected to the bus and load ground, a high voltage side switch is used. Often P-channel MOSFETs are used in this topology, again for voltage drive considerations. Determining the current rating The second step is to...Read more -
