DESCRIPTION
The third generation of MESH OVERLAY™ 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 souce. In this respect the 25V 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.
