Abstract: An electronic component includes first and second separate semiconductor regions. A third semiconductor region is arranged under and between the first and second semiconductor regions. The first and third semiconductor regions define electrodes of a first diode. The second and third semiconductor regions define electrodes of a second diode. The first diode is an avalanche diode.

Abstract: A protection device includes a first inductive element connecting first and second terminals and a second inductive element connecting third and fourth terminals. A first component includes a first avalanche diode connected in parallel with a first diode string, anodes of the first avalanche diode and a last diode in the string being connected to ground, cathodes of the first avalanche diode and a first diode in the string being connected, and a tap of the first diode string being connected to the first terminal. A second protection component includes a second avalanche diode connected in parallel with a second diode string, anodes of the second avalanche diode and a last diode in the string being connected to ground, cathodes of the second avalanche diode and a first diode in the string being connected, and a tap of the second diode string being connected to the third terminal.
