Other Product from Integrated Circuits. Because it rises as per the quote you must have an unstable power source of 5V and this is rising as you increase the load resistance.

Dqtasheet to find a datasheet for your specific zeners which shows the breakdown characteristics. In my experience, low-voltage zeners anything below 5V all seem to have a very soft ‘knee’ and not particularly ‘vertical’ current-vs-voltage curve.

WhatRoughBeast 49k 2 28 Spehro Pefhany k 4 Does this conflict with what Kvegaoro is saying? Home Questions Tags Users Unanswered. Email Required, but never shown. Zener impedance is measured at two points to insure a sharp knee on the breakdown curve and to eliminate unstable units 2.

I see your edited? The dynamic resistance describes the small-signal behavior near the test current.

Post as a guest Name. This item cannot be shipped to United StatesPlease contact seller to resolve this.

If you include the dynamic resistance in the model, you must use a lower voltage for the ideal zener. Since you are driving datasheft than 10 times that amount of current through it, it is no wonder that your voltage is high.

As shown in the circuit below which models the behavior that you are seeing of a voltage reading of about 4V from the zener diode. The problem is how you are modeling your circuit, because the series resistance you are using is so close the zener resistance, it must included in the circuit model.

Actually, as it happens I had reached the same conclusion. I’m not sure what the temperature coefficient is for this device and the data sheets are lacking in that respect. Therefore a better model of the zener diode is the zener diode plus the zener resistance in series. For use in stabilizing and clipping circuits with high power rating.

What’s odd is that the BZX55C is showing more-or-less the same behaviour although with different resistors.

You don’t say what you saw there. Null dataheet, 10 22 If you want decent accuracy throw the zeners away and use some low dropout 3. Message Seller Online Chat.

Please give us your feedback about this page Click Here. It seems odd then that the datasheets would specify an Izt of 69mA if it didn’t show the zener in the best light. You may be on right but it sure makes working out the correct resistor value a chore. As I pointed out in my query, I used the test currents from the relevant datasheets as a guide.
