Abstract
An apparatus includes a first diode and a second diode connected in series between a first voltage terminal and a second voltage terminal, a switch connected between the first voltage terminal and the second voltage terminal, and a clamping threshold circuit connected between a common node of the first diode and the second diode, and a gate of the switch, wherein the clamping threshold circuit is configured such that in response to a voltage surge applied to the common node of the first diode and the second diode, the switch is turned on once the voltage surge is greater than a predetermined threshold.
