    Abstract: The present invention provides overvoltage circuit protection. Specifically, the present invention provides a voltage variable material (“VVM”) that includes an insulative binder that is formulated to intrinsically adhere to conductive and nonconductive surfaces. The binder and thus the VVM is self-curable and may be applied to an application in the form of an ink, which dries in a final form for use. The binder eliminates the need to place the VVM in a separate device or for separate printed circuit board pads on which to electrically connect the VVM. The binder and thus the VVM can be directly applied to many different types of substrates, such as a rigid (FR-4) laminate, a polyimide or a polymer. The VVM can also be directly applied to different types of substrates that are placed inside a device.

    Abstract: An arrangement of voltage variable materials for the protection of electrical components from electrical overstress (EOS) transients. A device having a plurality of electrical leads, a ground plane and a layer of voltage variable material. The voltage variable material physically bonds the plurality of electrical leads to one another as well as provides an electrical connection between the plurality of electrical leads and the ground plane. A die having a circuit integrated therein is attached to the ground plane. Conductive members electrically connect the plurality of electrical leads to the integrated circuit. At normal operating voltages, the voltage variable material has a high resistance, thus channeling current from the electrical leads to the integrated circuit via the conductive members. In response to a high voltage EOS transient, the voltage variable material essentially instantaneously switches to a low resistance state, channeling the potentially harmful EOS transient to the ground plane and away from the integrated circuit.

    Abstract: The present invention provides connectors having circuit protection. Specifically, the present invention provides a device that operates with existing or new connectors to provide overvoltage protection to same. The device includes a strip of conductive material along which voltage variable material (nullVVMnull) is applied. The strip also includes an exposed portion not having the VVM deposition. The VVM contacts a plurality of signal conductors of the connector. The exposed portion contacts at least one ground conductor of the connector. When an overvoltage condition Occurs along one of the signal conductors, the VVM switches from a high impedance to a low impedance state, allowing the transient threat to dissipate, at least in part, to one or more ground conductor.

    Abstract: The present invention provides an ESD apparatus that includes an electrical overstress suppression device in series with a capacitor. The ESD apparatus is ideally suited for use with network communication devices, but any electronic device requiring overvoltage protection and isolation may employ the ESD apparatus of the present invention. In one embodiment, the ESD apparatus includes a capacitor and an electrical overstress protection device that electrically communicates in series with the capacitor. In another embodiment, the ESD apparatus includes an electrical overstress protection device having a voltage variable material and a capacitor that electrically communicates in series with the overstress protection device. The capacitor is sized so that the overstress device can withstand an application of a predetermined steady state voltage.
