Diodes were the first semiconductor electronic devices.

Today most diodes are made of silicon, but other semiconductors such as germanium are sometimes used.

We kingtronics have very strong offer for diode as a ISO 9001:2008 manufacturer.

We could provide you very excellent price with good quality.

We give good support to customers, many customers highly evaluated us, they said " we never meet any problem with kingtronics products, they have extremely quality, and the delivery time always is on time Like FedEx services". So kingtronics is really your reliable supplier!

Below is our new picture for some diodes. You can see our other products by visit our website: www.kingtronics.com

Rectifier diodes (large current)

Rectifier diodes are used in power supplies to convert alternating current (AC) to direct current (DC), a process called rectification. They are also used elsewhere in circuits where a large current must pass through the diode.

All rectifier diodes are made from silicon and therefore have a forward voltage drop of 0.7V. The table shows maximum current and maximum reverse voltage for some popular rectifier diodes. The 1N4001 is suitable for most low voltage circuits with a current of less than 1A.

Come here, You will get the right way to find excellent diode!

Kingtronics is ISO 9001: 2008 manufacturer of diode and Trimming Potentiometer and radial ceramic capacitors.

We have own brand kingtronics with trade mark kt,king,kingtronics.

Diode is one of our strong series. We offer a wide range of diode.

Below you can find popular part number, see:

Diode M7, S1M, LL4148, RS1M, SM4007 melf, BZV55C & ZMM55C, UF4007, 1N4001S-1N4007S, 1N4001-1N4007, 1N5391-1N5399.RL201-RL207, 1N5400-1N5408, 6A05-6A10, FR101-FR107, 1N4933-1N4937, FR151-FR157, FR201-FR207, 1N5817-1N5819, 1N5820-1N5822;

A Zener diode is a special kind of diode which allows current to flow in the forward direction same as an ideal diode, but will also permit it to flow in the reverse direction when the voltage is above a certain value known as the breakdown voltage. A Zener diode exhibits almost the same properties, except the device is specially designed so as to have a greatly reduced breakdown voltage.

The Zener diode's operation depends on the heavy doping of its p-n junction allowing electrons to tunnel from the valence band of the p-type material to the conduction band of the n-type material.

All such diodes, regardless of breakdown voltage, are usually marketed under the umbrella term of "Zener diode".
Kingtronics have much better prices offer for below zener diode, especially BZX55C and BZV55C.

In 1938, German scientist Walter Schottky developed a diode having a metal to semiconductor junction.

A Schottky diode, like other solid-state diodes, conducts electrical current in one direction.

It can operate at higher speeds than typical silicon diodes.

Advantages

Small pockets of electric charge build up in a typical silicon diode, slowing down its ability to turn current off.

A Schottky diode can operate hundreds of times faster since it avoids build up of electric charges.

It also has less than half the voltage drop conducting in the forward direction than a silicon diode.

Applications

Engineers use Schottky diodes in very high-frequency circuits, such as microwave transmitters.

Schottky diodes also see use in switching power supplies and solar battery charging systems.

Kingtronics produce and sell schottky diode 1N5817-1N5819, 1N5820-1N5822. if you have inquiry, pls send email to anna@kingtronics.cn.

Silicon diodes act as one-way valves for electrical current, allowing it to flow in only one direction. Like any electronic component,

diodes can fail from excessive voltage or current. Fortunately, diodes are simple to test, needing only a good multimeter to check them.

If you set the multimeter to read resistance and put the probes across the diode, you should read a low resistance one way and high resistance

with the probes reversed. A shorted diode will read low resistance both ways, and a blown diode will read high resistance both ways.

Instructions

1.Turn off the power to your circuit or equipment. Let the equipment sit for at least 30 minutes before removing the case or cover to allow the power supply to discharge。

2.Locate the diodes you want to test. They are typically small, two-lead parts with a stripe on the body to indicate the diode's cathode side.

3.Turn the multimeter on and turn the function knob so it points to the resistance setting. Hold the plastic body of the probes and are not touching the metal tips.

Touch the tip of the positive probe to one side of the diode and the negative probe to the other side. Read the resistance measurement and write it down.

Reverse the probes so they're touching the opposite sides of the diode. Write down the resistance you read . The higher resistance should be at least 10

times greater than the lower one. If it's less than five, the diode is very likely bad.

Kingtronics produce many types of diode rectifier,such as silicon diode, switching diodes, fast recovery diodes zener diodes.... Pls visit our updated website www.kingtronics.com for the details.

Any inquiry, pls send to anna@kingtronics.cn . Many thanks!
