Please be advised datasheett only post services such as China Post, EMS are permitted to deliver private packages to Russia. The ones with voltage of 5.

If you include the dynamic resistance in the model, you must use a lower voltage for the ideal datsheet. For all private orders, please choose from among those companies only. Rather than use rules of thumb which you may or may not understand, you should first look at the data sheet of the part you’re using. Sponsored Products are advertisements for products sold by merchants on DHgate.

Try to find a datasheet for your specific zeners which shows the breakdown characteristics. Actually, it was a candidate for a regulated supply fed by a CCS. The dynamic resistance describes the small-signal behavior near the test current.

I suspect that if you retest the “1N” parts with a test current of something like 20mA 70 ohms you may find that they’re within spec voltage-wise. Submit a Buying Request Let us help you find what you need. Reference Currency Datasheer Actually, as it happens I had datasheet the same conclusion.

You May Also Like. The closer to the minimum input voltage the more difficult it will be to avoid large changes in current flowing through the TL Therefore a better model of the zener diode is the zener diode plus the zener resistance in series.

Can I still get a reliable voltage if Vcc dips below 5V? Sign up using Facebook.

For use in stabilizing and clipping circuits with high power rating. It’s like the Zener resistance isn’t decreasing as the current increases, which datashset not what I’d expect. Does this conflict with what Kvegaoro is saying?

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

If you want to get 3. Can you expand on the statement: Since you are driving more than 10 times that amount of current through it, it is no wonder that your voltage is high.

This query was simply to highlight my dismay at 11n4729 poor these zeners really are!

If you want decent accuracy throw the zeners away and use some low dropout 3. Datasbeet out the current limiting resistor we have: As I pointed out in my query, I used the test currents from the relevant datasheets as a guide.

There are a couple of issues here. You do not see 3. Due to possible delay of exchange rate update, price in various currencies is for reference only. I don’t get it, where did the 9ohms come from? Typically the dynamic resistance of the 1NA is about 5 ohms, so you could approximate it with an ideal 3. 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.
