Abstract
A current limiter component constituted by a semiconductor bar or wafer doped in four layers (P, N, P, N) between its anode and cathode. The doping characteristics and the dimensional characteristics of the bar are adjusted to obtain a characteristic current to voltage curve which initially increases as voltage and current increases in the manner of a diode followed by a part constituting a current limiting plateau wherein the plateau reflects that the current remains fixed until the voltage reaches a breakdown voltage.
