DESCRIPTION
The SuperMESH™ series is obtained through an
extreme optimi za tio n of ST’s well established stripbased PowerMESH™ layout. In addition to pushing
on-resistance significantly down, spec ial care is taken to ensure a very good dv/dt capability for the
most demanding applications. Such series complements ST full range of high voltage MOSFETs including revolutionary MDmesh™ products.

PROTECTION FEATURES OF GATE-TO-SOURCE ZENER DIOD ES
The built-in bac k - to-back Zener diodes have spec if ically been designed to enhance not only the device’s
ESD capability, but a lso to make them safely absorb possible voltage transients that may occasionally be
applied from gate to source. In this r es pec t 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.
