INTRODUCTION

Power MOSFETs have become the standard choice as the main switching device for low-voltage (

There are several factors which affect the gate of the MOSFET, and it is necessary to understand the fundamental basis of the device structure before the MOSFET behavior can be explained. This application note details the basic structure of the Trench MOSFET structure, identifying the parasitic components and defining related terminology. It also describes how and why the parasitic parameters occur.
