MANUFACTURING YIELDS
DESCRIPTIONThe MDmesh™isa new revolutionary MOSFET tech-
nology that associates the Multiple Drain process with
the Company’s PowerMESH™ horizontal layout. The
resulting product has an outstanding low on-resis-
tance, impressively high dv/dt and excellent avalanche
characteristics. The adoptionof the Company’s propri-
etary strip technique yields overall dynamic perfor-
mance thatis significantly better than thatof similar
competition’s products.
APPLICATIONSThe MDmesh™ familyis very suitable for increasing
power densityof high voltage converters allowing sys-
tem miniaturization and higher efficiencies.
