Abstract
A low-capacitance bidirectional device of protection against overvoltages, intended to be used at high frequencies, including first and second discrete one-way Shockley diodes, the cathode and the anode of the first diode being respectively connected to the anode and to the cathode of the second diode, the break-over voltages of each diode ranging between 50 and 125 V.

A low-capacitance bidirectional device of protection against overvoltages, for use at high frequencies, including first and second discrete one-way Shockley diodes, a cathode and an anode of the first diode being respectively connected to an anode and to a cathode of the second diode, the break-over voltages of each diode ranging between 50 and 125 V.
A method for manufacturing a bidirectional device of protection against overvoltages, for high-frequency applications, including the steps of.
- forming two Shockley diodes on two distinct monolithic circuits, each diode having a break-over voltage ranging between 50 and 125 V;
- and
- connecting a cathode and an anode of the first diode respectively to an anode and to a cathode of the second diode.
