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 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.
