What should I do if the ESD diode experiences DC breakdown?

Under what conditions will electrostatic diodes experience DC breakdown?

In general, when the reverse voltage on the diode exceeds the maximum withstand value, it will be broken down. At this point, if the current is not limited, permanent damage will occur irreversibly. If the current is limited during breakdown, not only will it not be damaged, but it will also have a voltage stabilizing effect, just like a voltage stabilizing diode, because the volt ampere characteristic curve near the breakdown voltage is very steep.

A voltage can correspond to several current values, as long as the current is controlled within the rated range (using a series resistor to limit the current method), now simple voltage stabilizing circuits do this.
