Gallium nitride electromagnetic pulse arrestor

Patent ·
OSTI ID:1892544

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.
