Abstract
A current-limiting surge protection device is provided. The current-limiting surge protection device includes a pair of series connected normally on MOSFET's and a pair of voltage controlled normally off switches that are disposed to monitor a voltage across the normally on MOSFET pair. Here, the voltage controlled normally off switches close according to an excess threshold voltage across the MOSFET pair and reduces a gate drive potential of the normally on MOSFET pair to limit a current through the normally on MOSFET pair.
