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 MOS-
FETs including revolutionary MDmeshTM products.


APPLICATIONS
s HIGH CURRENT, HIGH SPEED SWITCHING

s IDEAL FOR OFF-LINE POWER SUPPLIES,

ADAPTORS AND PFC
s LIGHTING
