Causes and Prevention of MOSFET Failure
The two main causes of MOSFET failure: Voltage failure: that is, the BVdss voltage between the drain and source exceeds the rated voltage of the MOSFET and reaches a certain capacity, causing the MOSFET to fail. Gate Voltage Failure: The gate suffers an abnormal voltage ...Read more -
What can I do to fix my MOSFET that is heating up badly?
Power supply circuits, or power supply circuits in the field of propulsion, inevitably use MOSFETs, which are of many types and have many functions. For switching power supply or propulsion applications, it is natural to use its switching function. Regardless of N-type o...Read more -
MOSFET conduction characteristics
MOSFET conductivity means that it is used as a switch, which is equivalent to a switch closing.NMOS is characterised as conducting when Vgs exceeds a limited value, which applies to the condition with the source connected to a grounded device, and only needs the gate vol...Read more -
MOSFET Operating Characteristics
In fact, from the name, the power MOSFET is that it can work again when the output current is larger, MOSFET classification is divided into many kinds, which around the characteristics of the power consumption we can be divided into enhancement and depletion of type, if ...Read more -
Analysis of the reasons for the ineffectiveness of MOSFET

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 -
