MOSFET power dissipation is the sum of the conduction loss and the switching losses. These power losses are very different from each other. Conduction loss is the static loss wherein the main contributor is the drain to source on-state resistance of the MOSFET as well as the drain current. While switching losses are dynamic losses that are dependent on the

MOSFET could be used as a switch or amplifier. Regardless of the application, there is a conduction loss. Let’s explore what is the meaning of conduction loss and how to compute MOSFET conduction loss. Conduction loss is the main contributor to MOSFET power dissipation when operating in a non-switching application. Even in switching applications, conduction loss is still very significant

How to get MOSFET correct RDSon value is the pre-requisite to compute the MOSFET conduction loss or static power dissipation. RDSon is the drain to source on-state resistance of the MOSFET. The term “correct” is relative to the target result. Supposing the target is to compute the maximum power dissipation, then the correct RDSon value must be the worst-case value.

There are two types of losses in MOSFET. One is conduction loss and the other one is switching loss. Conduction loss is explained in detail here. Switching loss is not as easy as computing the conduction loss. There are many parameters to consider. You need to understand these parameters to select the correct values. However, you don’t need any more

MOSFET will not work if the gate to source voltage is not satisfied. VGS threshold is one of the specifications in the datasheet. However, it needs little understanding on how to determine the right VGS threshold. This article will discuss how to determine the correct MOSFET VGS threshold. How to Determine the Correct MOSFET VGS Threshold from the Datasheet To

Circuit breaker is the most common short circuit and over current protection. It is a simple electrical device but very important to safety. The most common question is what the current rating of the breaker will be to safely protect devices during abnormal condition. Basically, this is not the only thing to consider in selecting a circuit breaker. Below are

How simple a resistor is but it is very important in any circuits. A resistor role is to limit the amount of current flowing to the circuit. Without it, other electronic parts, circuits, modules or sub-circuits will not work. There are some factors to consider on how to select resistors. All these factors will be discussed below. These will give

A capacitor is everywhere. In power supply, LED lighting, in commercial electronics, in signal processing, etc., you need a capacitor. What is its specific role basically? A capacitor has several roles. It will eliminate noise issues on the circuit, working as a filter. It is the major part in low pass, high pass, band pass, band stop filters and so
