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 ...

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 presented solution for measuring voltage of Zener diodes using Arduino is completely new and original. The circuit uses LM317 as a constant current source and the whole measurement process is ...

Diodes are essential components found in electronic circuits. They allow current to flow in one direction while blocking it in the other. With time and usage, diodes can become defective, leading to ...

In this tutorial, we will study the behavior of a diode reverse-biased by a Dirac pulse, subsequently considering the special (and unpublished) case of a Zener diode. In this tutorial, we will study ...

Normally, when you want a low DC voltage from the AC line, you think about using a transformer of some kind. [RCD66] noticed that an AC monitor meter must have some sort of power supply but had no ...

A hardware project designed to provide a regulated DC supply using a Zener diode, eliminating the need for disposable batteries in low-power electronic devices like multimeters. To develop a stable ...

We always enjoy [w2aew’s] videos, and his latest on zener diodes is no exception. In it, he asserts that all Zener diodes are not created equal. Why? You’ll have to watch the video below to find out.
