For low voltage shunt regulation either use a series regulator LDO satasheet a device such as the TL which has a band gap reference, and an opamp in a 3-poin package to create an almost perfect “Zener diode”. Zener impedance is measured at two points to insure a sharp knee on the breakdown curve and to eliminate unstable units 2. Can I still get a reliable voltage if Vcc dips below 5V? Email Required, but never shown.

Even so I expect that the diode you have does match its data sheet.

What’s odd is that the BZX55C is showing more-or-less the same behaviour although with different resistors. First this stated in the question: View Cart 0 items. I suppose the point is, at 70mA, according to the datasheet, the voltage across the zener should be 3. I have a question about the regulation accuracy or lack of of a 3V6 Zener diode. Reference Currency HKD You may be on right but it sure makes datwsheet out the correct resistor value a chore.

There are a couple of issues here. This item cannot be shipped to United StatesPlease contact seller to resolve this.

Submit a Buying Request Let us help you find what you need. 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 Also Like. Both Zeners came from separate suppliers. If you include the dynamic resistance in the model, you must use a lower voltage for the ideal zener. Post as a guest Name. The closer to the minimum input voltage the more difficult it will be to avoid large changes in current flowing through the TL The dynamic resistance describes the small-signal behavior near the test current.

If you want to get 3. If you want decent accuracy throw the zeners away and use some low dropout 3. Actually, it was a candidate for a regulated supply fed by a CCS. 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. Working out the current limiting resistor we have: You don’t say what you saw there. Valid provided that electrodes at a distance of 10 mm from case are kept at ambient temperature 3.

How much current will th load require? Null 4, 10 22 This query was simply to highlight my dismay at how poor these zeners really are! Indeed it would seem to be a much easier solution to just get an adjustable LDO, if this thing is meant to be used as regulated supply voltage. Zeners with nominal voltages less than 5V or so have very soft ‘knees’ poor regulation and are not really that useful as usually better alternative are available.

Silicon Standard reserves the right to make changes as it deems necessary to any products described herein for any reason, including without limitation enhancement in reliability, functionality or design. Because it 1nn4729 as per the quote you must have an unstable power source of 5V and this is rising as you increase the load resistance.

Zeners are notoriously power inefficient even at no load. I set up the standard test circuit shown below. For use in stabilizing and catasheet circuits with high power rating.
