Features

Application

Description

The new SuperMESH3™ series is obtained

through the combination of a further fine tuning of

ST's well established strip-based PowerMESH™

layout with a new optimization of the vertical

structure. In addition to reducing on-resistance

significantly versus previous generation, special

attention has been taken to ensure a very good

dv/dt capability and higher margin in breakdown

voltage for the most demanding application.
