DESCRIPTION
The SuperMESHTM series is obtained through an
extreme optimization of ST's well established strip-
based PowerMESHTM layout. In addition to pushing
on-resistance significantly down, special care is tak-
en to ensure a very good dv/dt capability for the
most demanding applications. Such series comple-
ments ST full range of high voltage MOSFETs in-
cluding revolutionary MDmeshTM products.

GATE-SOURCE ZENER DIODE
PROTECTION FEATURES OF GATE-TO-SOURCE ZENER DIODES
The built-in back-to-back Zener diodes have specifically been designed to enhance 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 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.
