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 source. 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.
