DESCRIPTION
The MDmesh™ is a new revolutionary MOSFET
technology that associates the Multiple Drain pro-
cess with the Company’s PowerMESH™ horizontal
layout. The resulting product has an outstanding low
on-resistance, impressively high dv/dt and excellent
avalanche characteristics. The adoption of the
Company’s proprietary strip technique yields overall
dynamic performancethat is significantly betterthan
that of similar competition’s products.
APPLICATIONS
The MDmesh family is very suitable for increasing
power density of high voltage converters allowing
system miniaturization and higher efficiencies.
