The zener diode blue trace vz has a much sharper knee steeper slope and tighter voltage tolerance dashed lines and shaded region than a tvs.

Tvs diode applications. Various types of diodes with their characteristics applications. They include automotive and industrial grade transient voltage suppressor families as well as a host of diode array products for esd and emi. P n junction diode small signal diode rectifier diode schottky diode super barrier diodes light emitting diode led photodiode laser diode tunnel diode zener diode backward diode avalanche diode transient voltage suppression tvs diode gold doped diode constant current diode step recovery diode peltier or thermal diode vacuum.

Transient voltage suppression diode application notes technical note 4048 effective december 2017 tvs diodes tvs diodes tend to be designed with silicon avalanche technology.

When the normal voltage exceed to a certain level the tvs diode junction avalanches and as the result overvoltage is diverted from the protected circuit and shunted through the tvs diode. Zener and tvs i v characteristics compared although they appear similar a closer look at the i v characteristics in figure 5 immediately shows the differences. To provide full protection of the device against both positive and negative voltage spikes the tvs is constructed using two opposing sads in series figure 3.

Tvs diode application circuit in the normal voltage conditions tvs diode appears as an open circuit but a small leakage current is present. Voltage transients are defined as short duration surges of electrical energy and are the result of the sudden release of energy previously stored or induced by other means such as heavy inductive loads or lightning.
