DESCRIPTION
The MDmesh is a new revolutionary MOSFET
technology that associates the Multiple Drain process with the Company’s PowerMESH horizontal
layout. The resulting producthasanoutstanding low
on-resistance, impressively high dv/dtand excellent
avalanche characteristics. The adoption of the
Company’s proprietary strip technique yields overall
dynamic performancethat issignificantly better than
that of similar competition’s products.
APPLICATIONS
The MDmesh family isverysuitableforincreasing
power density of high voltage converters allowing
system miniaturization and higher efficiencies.
