How to Select a Diode for Circuit Design

Diode has many uses. It could be as a rectifier, a reverse blocking device, a component in a switching converter or in a switching power supply and so on. Regardless, what application it is, they are the same parameters to consider. These parameters are all given in the diode datasheet. If you are looking for guidance on how to select

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 detailed 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
