This paper presents a new compact model for ESD diodes named Advance SPICE Model for ESD diodes (ASM-ESD). In addition to the current-voltage (I-V) and the capacitance-voltage (C-V) behaviors of the diode under normal operating conditions, ASM-ESD has capabilities to model a plethora of important effects critical for the ESD applications. Model features include the ability to capture the overshoot effects, ambient temperature effects, self-heating effect, post reverse breakdown resistance, parasitic BJT gain, transient behavior of BJT gain and reverse recovery effects in ESD diodes. ASM-ESD model formulations have a physical basis leading to an intuitive extraction flow. Model comparisons with measurements for DC I-V, C-V, and TLP with pulse widths ranging from 200 ns to 1.2 ns are presented. These results demonstrate model accuracy for a full range of ESD event scenarios.
