ABSTRACT:
A voltage limiting device having gate and drain electrodes that include a serpentine configuration to form a pattern of breakdown corners at the traversals of the gate electrode over the drain electrode. The serpentine configuration may define a plurality of fingers. The number of breakdown corners determines the current-voltage (I-V) characteristics of the voltage limiting device. Either one of the gate electrode or the drain electrode may be configured in a manner to provide repeated traversals of one electrode over the other.
