Description
The SuperMESHTM series is obtained through an
extreme optimization of ST's well established
stripbased PowerMESHTM layout. In addition to
pushing on-resistance significantly down, special
care is taken to ensure a very good dv/dt
capability for the most demanding applications.
Such series complements ST full range of high
voltage MOSFETs including revolutionary
MDmeshTM products.
