DESCRIPTION
The SuperMESH™ series is obtained through an
extreme optimization of ST’s well established stripbased PowerMESH™ layout. In addition to pushing
on-resistance significantly down,specialcareis taken to ensure a very good dv/dt capability for the
most dem anding applications. Such series complements ST ful l range of high voltage MOSFETs including revolutionary MDm es h™ products.

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 t hem s afely absorb pos sible 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 prote ct the device’s integrity. These integrated Zener diodes thus avoid the
usage of external components.
