The 1N has a Vz of 4. However, there is a discrepancy when testing at 0. You can see the “knee” starting about at 1mA and ending at about 2mA. At this point we have to derive the various parameters from the datasheet of the component.

Assume we want to model a silicon diode 1N Sign up using Facebook. So then, I simulated the circuit with a current source instead of R1: If the reverse current is too low, they are either cut-off or just barely entering breakdown i. 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:. Although the operation of the diode is quite simple, extract a model from datasheet takes some time.

The extraction of the parameters of the table from the values reported in the datasheet, is not immediate for almost none of the parameters.

Which is it if either? This suggests it is the righter curve.

I simulated the following for various values of R, and the voltage drops quite a bit with small currents. Email Required, but never shown.

What’s the relationship between the current flowing through the Zener Diode?

Post as a guest Name. Home Questions Tags Users Unanswered. Adding more basic information to what Andy Aka already said: If you look on page 2 of the data sheeet it tells you the test current. We can take IBV as equal to 10 times Ir. You get the following results: Using linear scale you will get this: The zener voltage rating is right at the top edge of your graph the 20mA point. Sign up using Email and Password. 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:.

This gives a voltage of 2. By continuing to use our website you are agreeing to our use of cookies.

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. CJO can be directly equal to the value specified d17n50 the datasheet as Cj or Ctot, in this case is 4pF. Using linear scale you will get this:.

Relationship between Zener voltage and current? It looks like 0.

Other equations from the given parameters describing the capacitance of the junction, its evolution with temperature and more. 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 datasyeet Andy aka k 10 It’s nice if the simulator agrees but at this level of detail it doesn’t surprise or worry me.

For Zener diodes Ir can be called Izk, or in other cases as Ibr.

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! Usually for this type of diodes the value of IBV is around uA.

SPICE modeling of a Diode from Datasheet

Zener diodes are notoriously slack in their operating knee at low voltage ratings and this improves a lot when the voltage rises above 5V. Of course this doesn’t seem too sharp because of the logarithmic scale on the horizontal axis.

You can draw a plot of the reverse voltage vs. Sign up or log in Sign up using Google. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.
