Abstract of the Disclosure A solid state protector unit has a single voltage protection device shared by both tip and ring conductors to protect telephone equipment in a central office or other location from surges of voltages in either tip, ring, or both tip and ring conductors. The voltage device has a surge-suppressor sandwiched between two metal plates. Each of three pairs of metal spring clips retain a pair of diodes in contact with and on opposite sides of the two metal plates. When a voltage surge exceeds a predetermined threshold, the surge- suppressor turns on and permits a current to flow through it to a ground, thereby protecting the telephone equipment from voltage surges. Heat generated for a sustained period from the voltage device or from the current device will cause the current device to be grounded permanently.
