WebFor example, if I have a 16V Zener diode and a 12V power rail, the 16V Zener will protect the supply from transients above 16V. It will also prevent negative transients below -0.7V - say, if i reversed the battery. Why would placing two zeners in opposition improve this. Say if I placed two 15V Zeners in the same setup. WebAug 26, 2015 · The Zener voltage is the voltage at which the Zener diode conducts current when reverse biased. Figure 1 shows two Zener diode circuit symbols and the current-voltage plot of a Zener diode. The voltage across the terminals will be nearly constant between the breakdown current—or “knee current”—Iz (min) and the maximum current …
Webzener diode noise. This noise can be greatly reduced by connecting a capacitor between the Noise Reduction pin and ground. The capacitor forms a low-pass filter with R 6 (refer to the figure on page 1) and attenuates the high-frequency noise generated by the zener.
