摘要：
In an ESD device for fast switching applications based on a BSCR or NLDMOS-SCR, an anode junction control electrode is provided by not connecting the anode electrode to the collector of the BSCR or to the drain of the NLDMOS-SCR, and a cathode junction control electrode is provided by forming an additional n+ region in the BSCR or an additional p+ region in the p-well of the NLDMOS-SCR. The triggering voltage of the ESD device is adjusted after a time delay by controlling one or both of the control electrodes using an RC-timer-driver circuit.
