Critical Insights on Modeling of Transient Voltage Suppressor Diodes

This paper constitutes a brief critical review of the available mathematical models and equivalent circuits of transient voltage suppressor diodes. Furthermore, the implementation of modeling approaches in electromagnetic transient programs is demonstrated through their application for alternating and impulse current stress scenarios. Challenges in modeling the transient voltage suppression diodes are discussed in light of the deviations between simulation results and experimental data for commercially available bidirectional diodes.
