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 gat e to source. I n this respect the Zener voltage is appropriat e to ach ieve an effi cient
and cost-effective intervention to protect the device’s integrity. These integrated Zener diodes thus avoid
the usage of external components.
