Circuits and methods concerning voltage surge protection are disclosed. In an example embodiment, an apparatus includes a switching circuit configured to enable a current path between a first node and a second node in a first mode and disable the current path in a second mode. A biasing circuit configured to, in the surge protection mode, prevent a voltage surge at the first node from enabling the current path to the second node by biasing a voltage of the control node.
