Abstract: A transient voltage protection circuit includes an inductor with a source-side terminal and a device-side terminal, a first stage with a protection element connected to the inductor source-side terminal, and a second stage with a protection element connected to the inductor device-side terminal. A ground terminal is connected to the inductor device-side terminal through the first stage and to the inductor source-side terminal through the first stage. The second stage defines a single conductive path between the inductor source-side terminal and the ground terminal.
