Claim Text:
1. A lamp base comprising: a neutral contact including a first conductive metal surface; a line contact including a second conductive metal surface; a semiconductor transient protection device having three terminals, the semiconductor transient protection device formed as an integral component of the lamp base; a first terminal of the semiconductor transient protection device in mechanical and electrical contact with the neutral contact; a second terminal of the semiconductor transient protection device in mechanical and electrical contact with the line contact; a third terminal of the semiconductor transient protection device in electrical contact with a lead-in wire; a thermal element in series with the first terminal and the lead-in wire, the third terminal being a surface of the thermal element; a two-terminal semiconductor element in electrical connection with the first terminal and the second terminal, the two-terminal semiconductor element having an aperture in which the lead-in wire is located; and the semiconductor transient protection device configured to isolate the line contact from the neutral contact during a first line voltage input, and to provide a low-resistance shunt path between the line contact and the neutral contact during a second line voltage input.
