Kt Kingtronics How to Test Bridge Rectifiers and Zener Diodes

Bridge rectifiers and zener diodes are commonly used in electronic products such as computers and stereos. Bridge rectifiers are composed of a four-diode array.

These diodes convert alternating current into direct current. Bridge rectifiers have four leads, and are found in power supplies. Zener diodes are used to provide

regulated voltage for power supplies. A failure of either a bridge rectifier or zener diode prevents electronic devices from working properly.

Bridge Rectifier

  • Unplug the device that contains the bridge rectifier. This ensures the bridge rectifier is without power.
  • Set the digital multimeter, or DMM, to the "diode test" setting per the device's instructions.
  • Test the bridge rectifier diodes. Place the DMM's two leads on two adjacent rectifier pins. The DMM will read either "OL," indicating an open circuit; or a voltage of 0.7 volts DC or less. Switch the DMM leads. An operational bridge rectifier diode shows a reading opposite of the previous reading. Perform this test on each adjacent pair of bridge rectifier pins. The bridge rectifier is faulty if the readings are the same for any of the individual diodes.

Zener Diode

  • Unplug the device containing the zener diode. This ensures the zener diode has no power.
  • Set the DMM to the "diode test" setting.
  • Test the zener diode. Place the two DMM leads on the two zener diode leads. The DMM will read either "OL" or 0.7 volts DC. Switch the DMM leads. A working zener diode exhibits a second reading opposite of the first reading.

Kt Kingtronics zener diode

Zener diodes are widely used as voltage references and as shunt regulators to regulate the voltage across small circuits.

When connected in parallel with a variable voltage source so that it is reverse biased, a Zener diode conducts when the voltage reaches the diode's reverse breakdown voltage.

From that point on, the relatively low impedance of the diode keeps the voltage across the diode at that value.

Zener diodes are also used in surge protectors to limit transient voltage spikes.

We have much better prices offer for below zener diode, especially BZX55C and BZV55C.

Kt Kingtronics Diode

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

Kt Kingtronics capacitors

Kingtronics have very good quality for radial ceramic capacitors,  have ISO 9001:2008 certification. Here some features for your reference.

Class I capacitors: A typical class I capacitor will have a temperature coefficient of 30 ppm/°C. This will typically be fairly linear with temperature. Very high accuracy (~1%) class I capacitors are available (typical ones will be 5% or 10%). The highest accuracy class 1 capacitors are designated C0G or NP0.

Class II capacitors: A typical class II capacitor may change capacitance by 15% over a −55 °C to 85 °C temperature range. A typical class II capacitor will have a dissipation factor of 2.5%. It will have average to poor accuracy (from 10% down to +20/-80%).

Class III capacitors: A typical class III capacitor will change capacitance by -22% to +56% over a temperature range of 10 °C to 55 °C. It will have a dissipation factor of 4%. It will have fairly poor accuracy (commonly, 20%, or +80/-20%). These are typically used for decoupling or in other power supply applications.

There is a three digit code printed on a ceramic capacitor specifying its value. The value is given in picofarads (pF). A letter suffix indicates the tolerance:

C ± 0.25 pF M
±20%
D ± 0.5 pF P +100 −0%
J ± 5% S −20 +50%
K ±10% Z −20 + 80%

Kt Kingtronics Rectifier diodes (large current)

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.

Diode Maximum Current Maximum Reverse Voltage
1N4001 1A 50V
1N4002 1A 100V
1N4007 1A 1000V
1N5401 3A 100V
1N5408 3A 1000V

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
