What’s the relationship between the current flowing through the Zener Diode? It’s nice if the simulator agrees but at this level of detail it doesn’t surprise or worry me. Email Required, but never datasheett. Stick to the data sheet for most things but be prepared to do real tests on a batch if operating points significantly below test currents are required.
Datahseet, 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! It looks like 0.
Although the operation of the diode is quite datasjeet, extract a model from datasheet takes some time. You can see the “knee” starting about at 1mA and ending at about 2mA.
SPICE modeling of a Diode from Datasheet – YouSpice
The 1N has a Vz of 4. Zener diodes are notoriously slack in their operating knee at low voltage ratings and this improves a lot when the voltage rises above 5V. Assume we want to model a silicon diode 1N You can draw a plot of the reverse voltage vs. Relationship between Zener voltage and current?
CJO can be directly equal to the value specified in the datasheet as Cj or Ctot, in this case is 4pF. Other equations from the given parameters describing the capacitance of the junction, its evolution with temperature and more.
Andy aka k 10 This suggests it is the righter curve. All these parameters are used by SPICE to describe the behavior of the diode in the different situations of signal, for example in direct polarization in DC that, forward current will be:. Sign up using Facebook. Using linear scale you will get this:. I simulated the following for various values of R, and the voltage drops quite a bit with small currents.
Usually for this type of diodes the value of IBV is around uA. The extraction of the parameters of the table from the values reported in the datasheet, is not immediate for almost none of the parameters.
Home Questions Tags Users Unanswered. So then, I simulated the circuit with a current source instead of R1: The zener voltage rating is right at the top edge of your graph the 20mA point. Which is it if either? Of course this doesn’t seem too sharp because of the logarithmic scale on the horizontal axis. Sign datasyeet or log in Sign up using Google.
