I don’t get it, where did the 9ohms come from? If you increase the resistor the voltage across the zener should go down.

Please be advised that only post services such as China Post, EMS are permitted to deliver private packages to Russia. The next problem is that at 70mA and 4 vatasheet, the power is 0.

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. Working out the current limiting resistor we have: However, Silicon Standard Corporation 1n7429 no guarantee or warranty, expressed or implied, as to datashret reliability, accuracy, timeliness or completeness of such information and assumes no responsibility for its use, or for infringement of any patent or other intellectual property rights of third parties that may result from its use.

If you want to get 3. We’ve selected the bestselling items in this category just for you! If you include the dynamic resistance in the model, you must use a lower voltage for the ideal zener. Advertisement Sponsored Products are advertisements for products sold by merchants on DHgate. Since you are driving more than 10 times that amount of current through it, it is no wonder that your voltage is high.

Even if it specified at 70mA, there is going to be some there and in this case it is not negligible therefore it must be incorporated in to your circuit model, that why your circuit analysis provides a different answer but adding the zener resistance to the model gives a solution that approaches more closely your result. This query was simply to highlight my dismay at how poor these zeners really are! Sign up using Facebook. Null 4, 10 22 The dynamic resistance describes the small-signal behavior near the test current.

What output volta de you require? The dynamic resistance of the Zener may not be able to drop low enough, even with 70mA available to it, to make the proper resistor divider equivalent for the node to be equal to 3.

Zener impedance is measured at two points to insure a sharp knee on the breakdown curve and to eliminate unstable units 2.

Other Product from Integrated Circuits. The two Zeners in question are: If you want decent accuracy throw the zeners away and use some low dropout 3.

How much current will th load require? In fact, as I increase and decrease the resistor value, the Zener voltage increases and decreases along with it. Message Seller Online Chat. Andy aka k 10 I have a question about the regulation accuracy or lack of of a 3V6 Zener diode.

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.

Typically the dynamic resistance of the 1NA is about 5 ohms, so you could approximate it with an ideal 3. I suppose 11n4729 point is, at 70mA, according to the datasheet, the voltage across the zener should be 3.

Can you expand on the statement:
