Connect the zener diode across a variable or known such as 12v dc supply voltage source in series of 100w resistance and then connect the zener diode reverse bias cathode to red ve and anode to black ve test leads of multimeter as shown in fig. A second test you can do to check is a diode is with a voltmeter of a multimeter or simply just a voltmeter if you have one because diodes drop a specific voltage across their terminals with their threshold voltage is exceeded we can use these properties to see if a diode is reading a healthy and correct voltage across their terminals.

In this video i have explained the followings about zener diode.

How to test zener diode multimeter. A multimeter set to the resistance mode w can be used as an additional diode test or as mentioned previously if a multimeter does not include the diode test mode. Before going for the assembly of the basic electronic components in any particular circuit it is always advisable to test the components about their working condition or functioning to avoid the undesired outcome. A zener diode is a diode designed to operate in the breakdown region.

It maintains a constant voltage across the device so it is typically employed as a simple voltage regulator in many circuits. Application of zener diodes 3. How to test a zener diode as compared to the testing of normal diode zener diode testing needs some extra circuitry.

A diode is forward biased when the positive red test lead is on the anode and the negative black test lead is on the cathode. These conditions destroy normal diodes but a zener conducts a small amount of current. You can use any multimeter to test whether it is functional but a digital multimeter with a diode check function will give best results.

To check one use a multimeter to. A second test you can do to check to see whether a zener diode is defective or not is to measure its voltage with a voltmeter of a multimeter or simply just a voltmeter if you have one in order for this test to work we must feed voltage to the zener diode in reverse bias in series with a resistor. What is zener diode 2.

Because the zener diode conducts in reverse biased condition only if the applied reverse voltage is more than the zener breakdown voltage. How to test zener voltage of a zener diode with zener tester using 3nos. How to test a diode with a multimeter.

Most modern diodes are made from silicon but this reliable design can still break down when exposed to too much power.
