What is MOS tube
According to the purpose, it can be summarized as:
Ø ower Conversion
Ø Switch
Ø Rectify
Power MOSFET The application field is very wide. Because of the characteristics of the components, it can withstand low-voltage to high-voltage (12V-800V and above), small to large current (1A~200A..) and other applications. MOS tubes are distinguished between enhanced and depleted types.
Huashuo Semiconductor products are mainly enhanced MOS transistors. In the market, there are more and more enhanced MOS transistors and they are widely used.
MOSFET Compared with the general IC, the MOSFET package features low pin count and high heat dissipation requirements. The types are different according to customer design requirements. The commonly used package shapes are as follows:
Huashuo's MOS tube has two different types of products, N-channel and P-channel MOS.
How to choose between N-channel and P-channel products is based on the client application design.
Brief description of MOS tube electrical properties
Before briefly describing the MOS tube, you must first explain-when inquiring about the development plan with the customer, First, check the customer's demand for MOS tube? What is it? Is it N-channel or P-channel or N+P or N+N-channel MOS tube? When the customer needs type is solved, then go to check electrical demand.
A. Bvdss:
This item is the main item for checking customer needs. How much V MOS tube does the customer need? 30V, 40V or 100V?
B. ID:
After confirming how many V (volt) MOS transistors the customer needs, it is necessary to confirm whether the customer has how many IDs and how many A (amps) requirements.
C. VGS:
It refers to the voltage from Drain (drain) to Gate (gate or gate). Generally speaking, low-voltage MOS transistors are usually 20V. High-voltage MOS transistors are usually ±30V. Some low-voltage MOS transistors require ±12V. It depends Depending on the client application.
D.Vgs(th):
VGS(th) refers to how much V voltage is needed to start the MOS tube. There are 3 types of Min, Typ and Max in the upper the same value. When the MOS tube is made, the value of VGS(th) will be in Min ~ The Max definition area means that it conforms to the original design specification. The actual starting voltage value is usually near the upper and lower values of the Typ value.
E. Rds(on):
Rds(on) refers to the resistance value from the drain to the source. This value is one of the main factors that affect the temperature change of the MOS tube during application. The smaller the resistance, the better in principle. But it must be based on Customer's actual application Choose the right MOS tube.
F. Ciss, Coss, Crss, Qg, Qgd….Dynamic value
The dynamic value parameter part is based on the actual application of the customer choose a suitable MOS tube. The dynamic value part is also one of the main reasons that affect the temperature change of the MOS tube application.
Mos tube mainstream brand introduction
Summary of Brand Market Application
The full English name of MOS tube is called MOSFET (Metal Oxide Semiconductor Field Effect Transistor), which is a metal oxide semiconductor field effect transistor, which belongs to the insulated gate type of field effect transistors. Therefore, MOS tubes are sometimes called insulated gate field effect tubes, or field effect tubes for short.
According to the purpose, it can be summarized as:
Ø Switch
Ø Rectify

Brief introduction of MOSFET working principle:
MOSFET is abbreviated as MOS tube. One of its main functions is to switch the current. It is like a valve in a water pipe that controls the flow of water.
The current in a semiconductor can be divided into electron flow or hole flow:
Work with electron flow: called N-type field effect transistor
Work with hole flow: called P-type field effect transistor
Huashuo's MOS tube has two different types of products, N-channel and P-channel MOS.
The simple distinction of MOS products is as follows:
1. Low-voltage MOS tube: 20V~80V, with N and P channels and N+P channel products. There are also electrostatic protection and non-static protection products.
2. Medium voltage MOS tube: 100V~200V, with N and P channel products.
There are also electrostatic protection and non-static protection products.
3. High voltage MOS tube: 400V~800V, N-channel products. Mainly packaged in TO-200AB and TO-220F.
How to choose between N-channel and P-channel products is based on the client application design.
