Here is a handy zener diode tester which tests zener diodes with breakdown voltages extending up to 120 volts. The main advantage of this circuit is that it works with a voltage as low as 6V DC and ...

The circuit presented here is compact and handy for measuring the voltage rating of a Zener diode instantly. To check a Zener diode, it is connected across a DC power supply with a suitable resistor ...

The circuit has been constructed to test and measure the voltage rating of zener diodes. To be able to test the voltage rating of a zener diode up to 50 VDC, a small transformer and a single 555 timer ...

The circuit was designed to provide a means for measuring the operating voltage of zener diodes before applying on a circuit. Zener Diode – a special kind of diode that permits the flow of current in ...

In this page I present my approach to building a Zener diode tester. There are of course several DIY versions on the internet, but I have a few requirements... I am often confronted with switching ...

This Design Idea describes a versatile test circuit for zener diodes after yet another misread zener diode had infiltrated the ranks of 1N4148 diodes assembled on a pc board. As a bonus, the circuit ...
