Circuit Diagram Zener Diode Characteristics. To draw the v i characteristic of zener diode and to determine zener breakdown voltage. Due to heavily doped its.
A series resistor r is typically required to produce a voltage drop v z across the loadin this circuit diagram the unregulated input voltage is v s and the regulated output voltage across the load is v l which is the same as that across the diodethe series resistor r provides a voltage drop. The zener diode specially made to have a reverse voltage breakdown at a specific voltage. Zener diode circuit diagram pdf vi characteristics of zener diode circuit diagram.
Its characteristics are otherwise very similar to common diodes.
Zener diode surface zeners subsurface zeners. Here the zener diode acts like an ordinary diode. The series resistance r absorbs the output voltage fluctuations so as to maintain constant voltage across the load. The diagram given below shows the v i characteristics of the zener diode.
