TVS Transient Behavior Characterization and SPICEBased Behavior Model

Abstract

A SPICE model for the transient behavior of TVS devices is presented. TVS devices under ESD stress do not turn on instantaneously and a transient overshoot can be observed at start-up. This model includes small signal RF behavior, quasi-static VI curve, inductive overshoot, conductivity modulation, snapback trigger delay and the ability to be used on any SPICE simulation.
