Compact electronic device for protecting from electrostatic discharge

摘要

A device for protecting a set of N nodes from electrostatic discharges, wherein N is greater than or equal to three, includes a set of N units respectively possessing N first terminals respectively connected to the N nodes and N second terminals connected together to form a common terminal. Each unit includes at least one MOS transistor including a parasitic transistor connected between a pair of the N nodes and configured, in the presence of a current pulse between the pair of nodes, to operate, at least temporarily, in a hybrid mode including MOS-type operation in a sub-threshold mode and operation of the bipolar transistor.

1. A device for protecting a set of N nodes from electrostatic discharge, N being three or more, comprising:
a set of N units respectively possessing N first terminals respectively connected to the N nodes and N second terminals connected together to form a common terminal, wherein each unit comprises at least one MOS transistor including a parasitic transistor connected between two terminals of the MOS transistor and configured, in the presence of a current pulse between the two terminals, to operate, at least temporarily, in a hybrid mode including MOS-type operation in a sub-threshold mode and operation of the bipolar transistor.
