DESCRIPTION
d uc
The SuperMESHTM series is obtained through an
extreme optimization of ST's well established strip-
based PowerMESHTM layout. In addition to pushing
P ro
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-
