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.

Finding a Bridge Rectifier? How to find the best Bridge Rectifier? Do nothing before you visit our site! We kingtronics is Specialty in design,manufacture of bridge rectifier! We are your best choice.

The bridge rectifier is the most commonly used full wave rectifier circuit for several reasons, one advantage of a bridge rectifier over a conventional full-wave rectifier is that with a given transformer the bridge rectifier produces a voltage output that is nearly twice that of the conventional full-wave circuit.

(1) It does not require the use of center-tapped transformer, and therefore can be coupled directly to the ac power line, if desired.
(2)Using a transformer with the same secondary voltage produces a peak output voltage that is nearly double the voltage of the full wave center-tapped rectifier. This results in the higher dc voltage from the supply.

Kingtronics have UL certification for bridge rectifier, pls see picture of our products, we are glad to get your inquiries!

We kingtronics always sell very good quality capacitors based on our own brand.

Zener diode transfers current forward and backward, while traditional diodes are only capable of transferring current forward.

Many different electronic systems use Zener diodes to control their circui's voltage levels.

While there are several ways of doing this, Zener diodes provide efficient voltage regulation without damaging the diode itself.

How Zener Diodes Work
Zener diode acts like a regular diode as current moves in a forward direction in its circuit.

However, when a large enough voltage is applied to the diode in the reverse direction, it travels against the current from the output to the input.

Zener diodes can limit the amount of current that passes through them so that the voltage going backward limits the voltage going forward.

Advantages
Zener diodes are very small and can be integrated into virtually any electronic device, especially small circuits that cannot accommodate other forms of voltage regulation technology.

Zener diodes are also relatively inexpensive and are compatible with most other systems, making them the preferred voltage regulation device.
