The SuperMESHTM series is obtained through an
extreme opyimization of ST's well established strip IPAK
based PowerMESHTM layout. In addition to push-
ing on-resistance significatly down, special care is Figure 2: Internal Schematic Diagram
taken to ensure a very good dv/dt capability for the
most demanding application. Such series comple-
ments ST full range of high voltage MOSFETs
icluding revolutionary MDmeshTM products
