PZU10B2A,115

Introduction

Diodes - Zener - Single, the PZU10B2A,115 application field and working principle. In electronics, a diode is a two-terminal electronic component with an asymmetric transfer characteristic, with low (ideally zero) resistance to current flow in one direction, and high (ideally infinite) resistance in the other.

Working Principle of Zener Diodes

A Zener diode is a special type of semiconductor diode device. It is designed to operate in the reverse-biased mode. When a certain reverse voltage, known as the Zener voltage or breakdown voltage, is reached, the diode starts to conduct in the reverse direction and allow a small current through it. The Zener voltage can be determined by the doping level and the junction structure of the Zener diode.

When a Zener diode is reverse-biased, the depletion layer decreases with the applied reverse voltage (VR). When the applied voltage reaches the breakdown voltage (VZ), the diode starts to conduct abruptly and the current starts to increase exponentially. This type of breakdown is called Zener Breakdown. The Zener breakdown is caused by Zener effect, which is a result of quantum-mechanical tunneling effect.

When the Zener diode is in Zener operation, the reverse current (IZ) flowing through the device is relatively constant. This current is called the reverse saturation current. The characteristics of the IZ-VZ curve of a Zener diode are not perfect, but they are fairly linear.
