Abstract
An overvoltage protection device (40) and a method for increasing the overvoltage current the device can carry. The overvoltage protection device (40) includes a Silicon Controlled Rectifier (SCR) (11) and an SCR enhance circuit (42). The SCR enhance circuit (42) provides the SCR (11) with an additional low resistance path to increase the amount of overvoltage shunt current the SCR (11) carries during an overvoltage event.
