DESCRIPTION
The third generation of MESH OVERLAYTM Power
MOSFETs for very high voltage exhibits unsurpassed
on-resistance per unit area while integrating back-to-
back Zener diodes between gate and source. Such ar-
rangement gives extra ESD capability with higher rug-
gedness performance as requested by a large variety
of single-switch applications.

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 appropiate 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.
