1. The bui lt-in b ack-to-back Zener diodes have specifically been designed to enhance not onl y 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 ex te r na l co mp on ents.
