A GaN diode EMP arrestor exhibits breakdown in <10 ns at reverse-bias voltage >20 kV. Additionally, the arrestor exhibits avalanche ruggedness at 1 kA/cm² in a 1 mm² device (i.e. 10 A absolute current) over a period of 500 ns following the onset of breakdown. Finally, the specific on-resistance in the forward direction is <20 mΩ cm².
