Circuit Diagram Of Zener Diode. The reverse biasing means the n type material of the diode is connected to the positive terminal of the supply and the p type material is connected to the negative terminal of the supply. Circuit symbol of zener diode.
The graph represents that the zener diode has resistance. Further it is shown that the graph of zener breakdown is not exactly vertical. The voltage across the zener diode is represented by the equation given by.
The major use of zener diode is in industrial and commercial applications.
Zener diodes have voltage values from less than 2 volts to several hundred volts and they can dissipate power ranging from 0 25 to 50 watts or more. Further it is shown that the graph of zener breakdown is not exactly vertical. Applications of zener diode. The basic diagram of zener diode as voltage regulator is given below to fix the current through the zener diode series resistance r is introduced whose value can be chosen from the following equation resistor value ohms v1 v2 zener current load current.
