In this article, we will explore the basic functions of the Zener Diode. This device resembles a compact cylinder, much like the conventional diode, with two terminals at the ends that can be wired or ...

[Kevin] doesn’t stock zener diodes anymore. Why? Because for everything he used to use zeners, he now uses TL431 bandgap voltage references. These look like zener diodes but have an extra terminal.

There are times when you need to bias a low-current load and simply didn’t want to add another voltage regulator, or where you need a reasonable level of voltage accuracy, so a simple voltage divider ...
