DESCRIPTION

The third generation of MESH O VERLAY™ 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 arrangement gives extra ESD capabil­ity with higher ruggedness 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 specif ically been designed to enhanc e not only t he dev ice’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 integrat ed Z ener diodes thus avoi d t he
usage of external components.
