Precautions for use:

Gate drive voltage: Be careful not to exceed the rated voltage too much, otherwise the MOS will be damaged, up to 20V without damage; In general, we also connect a diode to the grid to prevent reverse breakdown;
Heat dissipation: the power of this MOSFET can be up to 190W, so if the heat dissipation is not done well, there will be a great probability of damage to the entire circuit;
PCB layout: In the design of PCB, it is necessary to consider the parasitic inductance of the grid drive circuit, which can improve the switching speed and reduce the switching loss;
