An Improved Compact Model of Silicon-Controlled Rectifier (SCR) for Electrostatic Discharge (ESD) Applications

This paper describes the development of a SPICE equivalent-circuit model of the silicon-controlled rectifier (SCR) for electrostatic discharge (ESD) protection applications. The framework developed includes the equivalent circuit, models for the various components imbedded in the SCR, and model parameters' extraction. The new model is implemented into the industry standard Cadence SPICE and is verified against transmission line pulsing measured data.
