Abstract The main purpose of this report is to obtain a Zener diode tester using 555 timer. A 555 timer, which works in astable mode, is used to generate a pulse and then given to a transistor driven circuit to test the Zener diode. The voltage across the Zener diode under test is calculated. How to Test a Diode 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.
