rodDescription
te PThe SuperMESH™ series is obtained through an
extreme optimization of ST’s well established
lestrip-based PowerMESH™ layout. In addition to
sopushing on-resistance significantly down, special
bcare is taken to ensure a very good dv/dt
Ocapability for the most demanding applications.
-Such series complements ST full range of high
)voltage MOSFETs including revolutionary
t(sMDmesh™ products.
