All About Zener diode

Everything you need to know about zener diode:

Understanding zener diode part number and marking easily

Most electronic equipment used zener diode in the electronic circuitry. You must determine the value (voltage) first before you begin to test a zener diode. Without knowing the zener diode voltage , you can't really accurately test it. I will guide you on how to use a semiconductor databook to find out the voltage by reading on it's marking. Read this article and i'm sure you will like it.

Testing zener diode with an analog multimeter

Understanding the zener diode part number is just a first step and you need second step to complete the test. Faults in zener diode can be open, shorted or have leakage reading. If you treat a zener diode just like a normal diode, i can be sure that you will missed out testing a bad zener diode. You need a proper method to test it and analog meter is one of the best testing equipment to test it.
