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 integrit y. These int egrated Zener diodes thus avoi d t he
usage of external components.
