Graphing the V vs I relationship of diode using Square wave

Click For Summary
SUMMARY

This discussion focuses on graphing the voltage (V) versus current (I) relationship of a zener diode using a square wave input. The key equation referenced is I = Io (e^((qV)/(nkT)) - 1), which describes the exponential current behavior in diodes. Participants express confusion regarding the behavior of the diode at various voltage levels, particularly in the context of a square wave signal. The discussion highlights the importance of understanding the breakdown region and conduction characteristics of zener diodes.

Homework Statement


I am having trouble understanding what this picture is showing.

I know that in the case of a sine wave, the voltage below zero will not conduct much if it does not drop past the breakdown region. On the other hand, it will start to conduct and grow exponentially at about .5-.7 V. However, when I tried the XY(I vs V) mode for a zener diode this is the graph I got. What is going on at each dot?

Homework Equations


I = Io (e^((qV)/(nkT)) -1)
k = 1.38 *10 ^-23
