ABSTRACT:
The present invention relates to a component protecting against electric overloads likely to occur on a conductor in series with which is placed a detection resistor. The component includes a first cathode-gate thyristor and a second anode-gate thyristor, of the gate current or forward break-over type. The anode region of the first thyristor, formed on the lower surface side, is separate from the isolating wall surrounding the thyristor and the rear surface of the isolating wall is coated with a portion of an insulating layer.
