Share the right way to order MOS tubes

　　The MoS tube name comes from the English name Metal (metal), OXID (oxide), semiconductor (semiconductor), is a field-effect transistor, or a semiconductor called a metal insulator. Usually the FET (field effect tube) is generally used as a thin layer of silica as the insulator under the gate, so the usual MOS tube size is smaller than the ordinary bipolar transistor more power-saving, in many cases have replaced the transistor.

With the development of electronic industry, MOS tube has been widely used in industry, if ordering to unsuitable or bad MOS tube will affect the efficiency and cost of the whole electronic products, then how to choose the MoS tube correctly is very important, but not a certain professional knowledge and difficult, The following is by the Lixin electronics and share with you the correct way to order the MoS tube

1, first to determine the MoS tube

MOS tube manufacturers are generally produced by N-Channel and P-Channel MOS tube, before you buy to confirm which type you want to purchase, different types have different choice method. such as the n-Channel MOS tube, which is the MoS pipe ground, and the load connected to the main line voltage, so that the formation of a low-voltage side switch, so for the switch off or on the device required voltage considerations, it is recommended to choose the P-Channel MOS tube. If the MoS tube is connected to the bus and the load is grounded, it is usually recommended to select the P-Channel MOS tube for the voltage drive.

2, determine the MoS tube rated current

To determine the MoS tube rated current first from its own application of the product circuit structure, the general situation is somewhat similar to the voltage, its rated current should be the load in all cases can withstand the maximum current, so take into account the current pulse or pulse peak can be affordable. If the rated current is determined to determine the loss of conduction, because all of the circuit structure over time, there will be loss, only to ensure that the function of the circuit in the normal operation of the MoS tube to play its role;

3.MOS Tube switch performance

MOS tube, especially high-power MOS tube, its source and drain, source capacitance has been the most important parameters affecting its switching performance, in its high-power MOS switch to charge it, if the loss is too large, the switching speed is reduced, the device efficiency is also reduced, This is also a MOS tube manufacturers to consider when producing MOS tube.

To really understand the MOS tube structure, the principle of the above points alone is difficult to do, but if the general lack of expertise of friends want to buy MOS tube, I believe through the above several summary, will not feel strange again.
