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 performance that is significantly better than

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.
