Feb 09, 2015В В· Outlines Introduction of Zener Diode Construction of Zener Diode Working of Zener Diode Application of Zener Diode Numerical of Zener Diode 3. Introduction The zener diode is a silicon pn junction devices that differs from rectifier diodes because it is designed for operation in the reverse-breakdown region. Jan 08, 2018В В· In Experiment B, a 6v Zener Diode used is conducting (the bulb comes on) in reverse biased because the applied voltage is greater than its breakdown voltage and thus shows that the breakdown region is the region of operation of the zener diode. The current-voltage characteristic curve of the Zener diode is shown below.
