DESCRIPTION

The SuperMESH™ series is obtained through an

extreme optimization of ST’s well established strip-

based PowerMESH™ layout. In addition to pushing

on-resistance significantly down, special care is tak-

en to ensure a very good dv/dt capability for the

most demanding applications. Such series comple-

ments ST full range of high voltage MOSFETs in-

cluding revolutionary MDmesh™ products.
