Does this conflict with what Kvegaoro is saying?

1n44729a may be on right but it sure makes working out the correct resistor value a chore. I have a question about the regulation accuracy or lack of of a 3V6 Zener diode. The dynamic resistance describes the small-signal ddatasheet near the test current. The closer to the minimum input voltage the more difficult it will be to avoid large changes in current flowing through the TL It seems odd then that the datasheets would specify an Izt of 69mA if it didn’t show the zener in the best light.

I’m not sure what the temperature coefficient is for this device and the data sheets are lacking in that respect.

Spehro Pefhany k 4 I don’t get it, where did the 9ohms come from?

Dtaasheet this stated in the question: WhatRoughBeast 49k 2 28 Even so I expect that the diode you have does match its data sheet.

That part of kveagaro’s answer is not correct.

How much current will th load require? This query was simply to highlight my dismay at how poor these zeners really are!

See Fig 2 in diodes. In my experience, low-voltage 1n4729aa anything below 5V all seem to have a very soft ‘knee’ and not particularly ‘vertical’ current-vs-voltage curve. 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 datxsheet model gives a solution that approaches more closely your result.

What’s odd is that the BZX55C is showing more-or-less the same behaviour although with different resistors. Post as a guest Name. 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 simulate this circuit — Schematic created using CircuitLab.

There are a couple of issues here. Email Required, but never shown. It’s like the Zener resistance isn’t decreasing as the current increases, which is not what I’d expect. Null 4, 10 22 Sign up using Facebook.

I suppose the point is, at 70mA, according to the datasheet, the voltage across the zener should be 3. I wanted to confirm that I wasn’t doing anything stupid. You do not see 3. I set up the standard test circuit shown below. Therefore a better model of the zener diode is the zener diode plus the zener resistance in series. For low voltage shunt regulation either use a series regulator LDO or a device such as the TL which has a band gap reference, and an opamp datxsheet a 3-poin package to create an almost perfect “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. Can you expand on the statement: In fact, as I increase and decrease the resistor value, the Zener voltage increases and decreases along with it.

Double check this supply. Indeed it would seem to be a much dstasheet solution to just get an adjustable LDO, datashest this thing is meant to be used as regulated supply voltage.
