It has low ideally zero resistance in one direction and high ideally infinite resistance in the other. A zener diode is a type of diode that allows current to flow in the conventional manner from its anode to its cathode ie. Zener Diode Power Rating Exceeded Electrical Engineering Scavenger S Blog Zener Diode And Linear Voltage Regulation Applications Of Zener Diodes Voltage Regulator Meter The diode consists of a special heavily doped p n junction designed to conduct in the reverse direction when a certain specified voltage is reached. What is a zener diode what is its use . Clarence zener is the scientist who discovered this electrical property and the device is named. This circuit provides safety for the equipment connected at the terminals. When the voltage across the terminals is reversed and the potential reaches the zener voltage or knee the junction ...
