ZENER DIODE PDF
A Zener diode is a type of diode that permits current to flow in the forward Current-voltage characteristic of a Zener diode with a breakdown voltage of 17 volt. FEATURES. • Silicon planar power Zener diodes. • For use in stabilizing and clipping circuits with high power rating. • Standard Zener voltage tolerance is ± 5 %. Section B9: Zener Diodes. When we first talked about practical diodes, it was mentioned that a parameter associated with the diode in the reverse bias region .

Zener Diode. Features. • High reliability. • Very sharp reverse characteristic. • Low reverse current level. • VZ-tolerance ±5%. Application. Electronics Tutorial about the Zener Diode and how the Zener Diode can be used with a series resistor to produce a Zener Diode Voltage Regulator Circuit. INTRODUCTION. The zener diode is a semiconductor device unique in its mode of operation and completely unreplaceable by any other electronic device.
A Zener diode is a type of diode that allows current to flow not only from its anode to its cathode, but also in the reverse direction, when the Zener voltage is reached. Zener diodes have a highly doped p—n junction. Normal diodes break down with a reverse voltage, but the voltage and sharpness of the knee are not as well defined as for a Zener diode. Normal diodes are not designed to operate in the breakdown region, whereas Zener diodes operate reliably in this region. The device was named after Clarence Melvin Zener , who discovered the Zener effect. Zener reverse breakdown is due to electron quantum tunnelling caused by a high-strength electric field. However, many diodes described as "Zener" diodes rely instead on avalanche breakdown.
