Abstract
A semiconductor device for protection from electrostatic discharge includes a number of modules for protection from electrostatic discharge. Each module includes a thyristor having terminals and a gate, and a diode coupled in antiparallel to the terminals of the thyristor. Each module is sized to share a saturation current with neighboring modules when an electrostatic discharge current is received. A resistive network couples modules between two terminals. A triggering circuit includes a common triggering output that is coupled to the gate of the thyristor of each module and a common buried semiconductor layer contacts each module.
