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.
