Eletronics Lab Report - Zener Diodes - Free download as PDF File (.pdf), Text File (.txt) or read online for free. Compute Vin(max) for the circuit ? VI characteristics of zener diode. When a zener diode operates in the breakdown region, it does not burn rapidly. We will then plot it to get the depen-dence. endobj However, the reason for this is some external circuit is required in order to protect the device from the excess current. For Zener diodes, silicon is preferred to Ge because of its high temperature and current capability. EGR220 Than & Bhavin Lab #1 Introduction and Objectives Although, nowadays, Zener Diodes are becoming less popular and virtually replaced with specially designed IC (integrated circuits), they are simple and useful. Zener diode is a silicon semiconductor with a p-n junction that is specifically designed to work in the reverse biased condition. A Zener diode not only allows current to flow from anode to cathode but also, in the reverse direction on reaching the Zener voltage. Properties of junctions Zener diode characteristics. Physics Practical Experiment | Study Material, Lecturing Notes, Assignment, Reference, Wiki description explanation, brief detail | ... VOLTAGE-CURRENT CHARACTERISTICS OF A ZENER DIODE . In the reverse bias condition the Zener diode is an open circuit and only a small leakage current is flowing as shown on the exaggerated plot. Objective: To study and verify the functionalityof Zener diode in forward bias and reverse bias and to Plot Volt-Ampere Characteristics of Zener 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. /Filter /DCTDecode When forward biased, it behaves like a normal signal diode, but when the reverse voltage is applied to it, the voltage remains constant for a wide range of currents. The V-I characteristic of Zener diode indicates that characteristic of Zener diode in forward bias is same as PN junction diode.
