What’s the relationship between the current flowing through the Zener Diode? I simulated the following eatasheet various values of R, and the voltage drops quite a bit with small currents. The 1N has a Vz of 4. The only information related to it on the datasheet I could find was the following, however I’m not sure what curve I’m meant to be looking at:. This suggests it is the righter curve. However, then I simulated the circuit at 0.
This gives a voltage of 2. Which is it if either?

The zener voltage rating is right at the top edge of your graph the 20mA point. If you look on page 2 of the data sheeet it tells you the test current. So, looking at your graph and ignoring the black line at the very left because they don’t seem to be specifying a zener voltage at that rating! Zener diodes are notoriously slack in their operating knee at low voltage ratings and this improves a lot when the voltage rises above 5V.
However, there is a discrepancy when testing at 0. It looks like 0. Stick to the data sheet for most things but be prepared to do real tests on a dataaheet if operating points significantly below test currents are required. It’s datasueet if the simulator agrees but at this level of detail it doesn’t surprise or worry me. Adding more basic information to what Andy Aka already said: If the reverse current is too low, they are either cut-off or just barely entering breakdown i. You can draw a plot of the reverse voltage vs.
You can see the “knee” starting about at 1mA and ending at about 2mA.
Of course this doesn’t seem too sharp because of the logarithmic scale on the horizontal axis. Using linear scale you will get this:.
