Kt Kingtronics bridger rectifiers

Bridge rectifiers

There are several ways of connecting diodes to make a rectifier to convert AC to DC. The bridge rectifier is one of them and it is available in special packages containing the four diodes required. Bridge rectifiers are rated by their maximum current and maximum reverse voltage. They have four leads or terminals: the two DC outputs are labelled + and -, the two AC inputs are labelled.The diagram shows the operation of a bridge rectifier as it converts AC to DC. Notice how alternate pairs of diodes conduct.

Various types of Bridge Rectifiers
Note that some have a hole through their centre for attaching to a heat sink

Kt Kingtronics zener diode

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.

Kt Kingtronics How Does a Schottky Diode Function?

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.


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.


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.

Kt Kingtronics How to Test Diodes: Silicon Diodes

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.


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.

Kt Kingtronics bridge rectifier

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!
