Abstract: A solid state protector device is disclosed for protecting a consumer's solid state electronic circuits from abnormal voltage and current surges. The device comprises an enclosure made of electrically non-conductive material having front, rear, side, top and bottom walls. A protector circuit is disposed in the enclosure for protecting electronic equipment from abnormal current and voltage surges. The protective circuit has an input terminal, an output terminal and a ground terminal. An input connector for receiving an input circuit signal is disposed in the front wall of said enclosure and electrically connected to the input terminal of said protector circuit. An output connector for conducting said circuit signal to the electronic equipment to be protected is disposed in the front wall of said enclosure and electrically connected to the output terminal of said protector circuit. A plug is used for connection to an outside ground and is disposed in the rear wall of said enclosure.

Abstract: A transient voltage surge suppressor for an AC powerline comprises two semiconductor voltage limiting devices before a low pass LC filter and a third semiconductor voltage limiting device after the filter. The suppressor can be plugged into a 120 volt receptacle for protection of sensitive electronic equipment.
