Abstract
In this paper, we analysed the properties of the conventional ESD protection devices such as SCR, MVSCR, LVTSCR. The electrical characteristics and the turn-on time properties are simulated by Synopsys T-CAD simulator. As the results, the devices have the holding voltages between 2V and 3V, and the trigger voltage of about 20V with SCR, of about 12V with MVSCR, of about 9V with LVTSCR. The results of the simulation for the turn-on time properties are 2.8ns of SCR, 2.2ns of MVSCR, 2.0ns of LVTSCR. Thus, we prove that LVTSCR has the shortest turn-on time. However, the second breakdown currents(It2) of the devices are 7.7A of SCR, 5.5A of MVSCR, 4A of LVTSCR. This different properties have to be adapted by the operation voltages for I/O Clamps.
