发明名称 Protection of electrical devices with voltage variable materials
摘要 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.
