Understanding On-Resistance and Its Impact on NDS331N MOSFET Performance
The NDS331N is a popular N-channel MOSFET used in a variety of applications such as power regulation, motor control, and load switching. It is valued for its low on-resistance (Rds(on)) and excellent switching characteristics. However, as with any complex semiconductor device, abnormal on-resistance can occur, leading to significant performance issues. In this part of the article, we will first understand what on-resistance is, how it impacts the performance of the MOSFET, and then look at the common causes of abnormal Rds(on) in the NDS331N.
