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.
