## How to Calculate MOSFET Power Dissipation

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

## How to Compute MOSFET Conduction Loss

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

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.

## How to Compute MOSFET Switching Losses

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

## How to Determine the Correct MOSFET VGS Threshold

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

## Important MOSFET Design Parameter to Consider

The important MOSFET design parameter to consider during circuit design are gate threshold voltage, on-state resistance, current stress, voltage stress, power stress and thermal stress to name few. All parameters will be discussed in this topic so keep reading. Threshold voltage refers to the gate to source voltage requirement for the MOSFET to turn on. On-state resistance is the equivalent

## How to Select a Circuit Breaker – Basic Tips

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 to Select Resistor – Selecting Resistor Ratings

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
