Assignee: INFINEON TECHNOLOGIES AG
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An overvoltage protection device, comprising:
first and second semiconductor devices arranged in an anti-serial configuration, the first and second semiconductor devices each being two terminal semiconductor devices with one way conduction characteristics;
a conductive link that forms a complete electrical connection between an internal terminal of the first semiconductor device and an internal terminal of the second semiconductor device at a central node of the overvoltage protection device;
a first terminal connection to a terminal of the first semiconductor device that is opposite from the internal terminal of the first semiconductor device;
a second terminal connection to a terminal of the second semiconductor device that is opposite from the internal terminal of the first semiconductor device;
wherein a total capacitance a first transmission path that is between the first terminal connection and the central node substantially matches a total capacitance of a second transmission path that is between the second terminal connection and the central node, and
wherein an entire self-capacitance of the conductive link is included in the total capacitance of the second transmission path.
