overvoltage protection device

1 Introduction

In order to reduce the power consumption, size and cost of electronic devices, most
semiconductor components are manufactured using a “low voltage” process resulting in
a maximum operating voltage of 7 V or even less. Any overvoltage causes an excessive
power dissipation on the chip quickly leading to damage, or even electrical breakdown.
Portable electronic devices, such
