Application
■ Switching applications
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.

1. The built-in back-to-back Zener diodes have specifically been designed to enhance not only the device’s
ESD capability, but also to make them safely absorb possible voltage transients that may occasionally be
applied from gate to source. In this respect the Zener voltage is appropriate to achieve an efficient and
cost-effective intervention to protect the device’s integrity. These integrated Zener diodes thus avoid the
usage of external components
