What Is the Slope Resistance of a Zener Diode?

Click For Summary
SUMMARY

The slope resistance of a Zener diode refers to the resistance value derived from the slope of the current versus voltage curve in reverse bias operation. This slope is indicative of the diode's behavior when it begins to conduct in reverse bias, and it can be calculated by linearizing the curve over a specific range of reverse bias. The slope resistance is not a fixed value but varies depending on the operating point within the reverse bias region.

Look at the plot of the Current versus Voltage for the diode in forward and revers bias. In reverse bias, where the Zener diode starts to conduct, there is a slope to the curve. That slope can be thought of as a "resistance", if you linearize (average) it over some range of reverse bias.
