When choosing a MOS tube, you must pay attention to the selected model, because in the circuit design, the heat dissipation power, drain-source voltage and current must be understood, and only a more matching MOS tube can be used normally.

MOS tube

There are many types of MOS tubes. In fact, no matter what type it is, you must pay attention to the requirements of the circuit when selecting it. Whether it is a switching circuit or a bias circuit, in fact, different MOS tubes are selected when they are selected. , but it must be understood that this kind of electronic component is a relatively precise component, so be sure to do a good job of electrostatic protection before use, such as packaging to use the packaging of metal bottle honey, and whether it is storage or transportation, it must be The pins should be short-circuited to prevent electrostatic breakdown. After all, such electronic components have a very high impedance and are easily broken down by static electricity. In addition, for the storage of such electronic components, do not put them in plastic boxes, it is better to put them in metal boxes, and pay attention not to be in a humid environment.
When using MOS tubes, in order to avoid electrostatic breakdown, all equipment must be grounded, and then it includes the circuit board itself, or measuring instruments and electric soldering irons, etc., and when soldering We must pay attention to distinguish the state of each corner, pay attention to welding the source first, and pay attention to the grounding state during the welding process of all pins. At the same time, we must pay attention to avoid the generation of static electricity as much as possible, and when welding, the requirements are relatively high, so we must pay attention when using it, so as not to weld well, and it turns out that the pipe is broken down. When installing, pay attention to the location and try to keep it as far away from the heating element as possible to avoid any influence. In addition, when the power of this kind of tube is high, a radiator should be installed, so the installation of the radiator should be considered, and the protection and heat dissipation should be considered. The connection of the device is tighter, and the heat dissipation effect can be achieved.
