DESCRIPTION
The SuperMESHTM series is obtained through an               INTERNAL SCHEMATIC DIAGRAM
extreme optimization of ST's well established strip-
based PowerMESHTM 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 MDmeshTM products.

APPLICATIONS
s HIGH CURRENT, HIGH SPEED SWITCHING
s IDEAL FOR OFF-LINE POWER SUPPLIES,

  ADAPTORS AND PFC
s LIGHTING
