INDUSTRY’S LOWEST ON-RESISTANCE
DESCRIPTION
The MDmesh™
is a new revolutionary MOSFET
technology that associates the Multiple Drain process 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.

PROTECTION FEATURES OF GATE-TO-SOURCE ZENER DIODES
The built-in back-to-back Zener diodes have specificall y been des igned to enhan ce not only the device’s
ESD capability, but also to make them safely absorb possible voltage transients that may occasionally be
applied from gate to source. In this respect the 25V Zener voltage is appropriate to achieve an efficient
and cost-effective intervention to protect the device’s integrity. These integrated Zener diodes thus avoid
the usage of external components.
