What is a voltage regulator diode, and what is the difference between a voltage regulator diode and a regular rectifier diode? 1

Zener diode is a common electronic component that can stabilize the voltage within a certain range, enabling the circuit to operate normally. Zener diodes are widely used in power supplies, SN74LVC1G125DBVR amplifiers, computers, communications, and other fields, and are an indispensable part of modern electronic technology. This article will provide a detailed introduction to the working principle, types, parameter selection, and applications of voltage regulator diode.

1、 The working principle of voltage regulator diode

Zener diode is a semiconductor device with PN junction structure, and its working principle is similar to that of ordinary diodes. Under forward voltage, the current of the voltage regulator diode is linearly related to the voltage, while under reverse voltage, the current of the voltage regulator diode changes exponentially. Therefore, the voltage regulator diode can achieve voltage stability through reverse voltage.

The working principle of a voltage regulator diode can be simply divided into two stages: forward conduction and reverse cutoff.
