A Brief Analysis of Planar and Trench IGBT Structures

Updated: 2023-10-09
Views: 12326

In the current IGBT surface structure, planar and trench types can be said to be evenly matched. When many readers first encounter these two terms, they may mistakenly think that the current of the planar IGBT flows horizontally, while the current of the trench-gate IGBT flows vertically. In fact, this is a misundersta……
