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 ...

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 belo… ...

Zener diodes as regulators The previous experience has made us understand that if a Zener diode inversely polarized goes to conduction, there is a fixed voltage, Vz, on it. For example, if there is ...

The circuit is designed with the ATMEGA328 microcontroller IC. The standalone Arduino technique is adopted here because of the popularity, economical, and easy-to-use features of Arduino IDE. This ...

Generally speaking, we try to avoid operating diodes in their reverse breakdown region, but Zener diodes are the exception to this rule. Generally ...

Zener Diode Tester Circuit The power supply section comprising transformer X1, rectifier diode D1, filter capacitor C1, resistor R1, transistor T1 and zener diodes ZD1 and ZD2 provides approximately ...

Zener diodes are one of those strange items that have several uses but are not as popular as they once were. There was a time when the Zener was a reasonable way to regulate a voltage ...

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 ...
