The Behavioral Models of Suppressors and Devices Based on Them

The results of modeling suppressors and protection devices based on them are presented in the form of a separate library using the Cadence software environment (OrCAD). The presented behavioral models of suppressors are developed for the domestic element base and allow more accurately representing the current-voltage characteristics in comparison with standard SPISE models. The behavioral models include typical SPICE components of the OrCAD software environment, such as passive elements, semiconductors, and controlled current and voltage sources. The protective devices include suppressors and assemblies based on them, designed to protect one line or two channels. The simulation results for low (100 Hz) and high (40 kHz) frequencies are presented. The studied protective devices have a high degree of protection against electrostatic discharges at an extremely low level of their own capacity, which allows them to be included in circuits with operating frequencies up to 3 GHz and successfully protect digital interfaces (USB, MHL/MDDI, LVDS, etc.), as well as multimedia ports of displays and memory cards.
