Parameter analysis and measurement of MOSFETs
There are many kinds of main parameters of MOSFET, which contain DC current, AC current parameters and limit parameters, but the general application only need to care about the following basic parameters: saturation state of the leakage source current IDSS pinch-off volt...Read more -
About MOSFET driver
In contrast to the dual spinning crystal triode, it is generally felt that making the MOSFET conduct does not use an electrical flow, but only requires the GS voltage to be higher than a certain value. It is relatively easy to do this, we mainly need a certain rate. For ...Read more -
Parallel Theory of MOSFETs and Transistors
About the basic theory of paralleling transistors and MOSFETs: Firstly, transistors have a negative exponential temperature value, that is to say, when the temperature of the transistor itself rises, the on-resistance will become smaller. Secondly, MOSFETs have a positiv...Read more -
Circuit situation of mosfet application
When designing a switching power supply or motor drive circuit with a mosfet, most people will consider the on-resistance of the mos transistor, the maximum voltage, and the maximum current, but that's all they will consider. Such a circuit may work, but it is not a high...Read more -

MOSFET Package Switching Tube Selection and Circuit Diagrams
The first step is to make a selection of MOSFETs, which come in two main types: N-channel and P-channel. In power systems, MOSFETs can be thought of as electrical switches. When a positive voltage is added between the gate and source of an N-channel MOSFET, its switch ...Read more
