What is a diode? A diode is a semiconductor device that essentially acts as a one-way switch for current. An ideal diode will have zero resistance in one direction, and infinite resistance in the reverse direction. They are also known as rectifiers because they change alternating current (AC) into pulsating direct current (DC).

Common package diodes in daily life, such as SOD123, SOD323, SOD523, SOT23, ZMM series LL34 package, ZM47**A series LL41 package, BZX55C series DO35 package and so on.

We will offer you a nice price whether it is a plastic package diode or a glass packaged diode. Let us know by info@kingtronics.com, if you are interested.

Zener diode is a particular type of sodium that allows current to flow not only from its anode to its cathode, but also in the reverse direction, when the so-called "Zener voltage" is reached. They are used in many circuits in a variety Of ways, like PSU with series transistor, voltage regulator, overvoltage protection.

A diode is an electrical component acting as a one-way valve for current. And diode is used in very wide range. 
Zener diodes are designed to be operated in reverse-bias mode, providing a relatively low, stable breakdown, or zener voltage at which they begin to conduct substantial reverse current.
A Zener Diode is a special kind of diode which permits current to flow in the forward direction as normal, but will also allow it to flow in the reverse direction when the voltage is above a certain value - the breakdown voltage known as the Zener voltage.

A zener diode may function as a voltage regulator by acting as an accessory load, drawing more current from the source if the voltage is too high, and less if it is too low .

About

Kingtronics International Company was established in 1995 located in Dongguan City of China to handle all sales & marketing for factories located in Chengdu, Sichuan and Zhaoqing, Guangdong, China. In 1990, we established the first factory to produce trimming potentiometer and in 1999 we built up new factory in Zhao Qing, Guangdong. Now with around 850 workers, Kingtronics produce trimming potentiometers, dipped tantalum capacitors, multilayer ceramic capacitors, and diode & bridge rectifier. We sell good quality under our brand Kingtronics, and Kt, King, Kingtronics are our three trademarks. All our products are RoHS compliant, and our bridge rectifier have UL approval. Please visit our Products page, you could please download all our PDF datasheet and find cross reference for our Trimming Potentiometer and capacitors.
