Sep 7, 2019 - Download Basic Electronics Notes on V-I Characteristics of Zener Diode including application of Zener Diode Voltage Regulator with brief explanation in pdf. 0 The limiting (maximum) power for a zener diode is given by P z=V zI zmax and is a function of the design and construction of the diode. However, the Zener Diode or Breakdown Diode, as they are sometimes referred too, are basically the same as the standard PN junction diode but they are specially designed to have a low and specified Reverse Breakdown Voltage which takes advantage of any reverse voltage applied to it. The relationship is obtained by applying KVL and it is Vs Vg R Im − = (1.10) Vs R + I-Figure 8.
