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 ...

A Zener diode is the simplest known type of voltage limiter (Figure 1) As soon as the voltage exceeds the rated voltage of the Zener diode, a current can flow through the diode to limit the voltage.

Abstract: Innovation in GaN semiconductors has improved aspect of power capability, switching speed and size. However, their short-circuit withstand time is low compared to SiC and IGBT switches. It ...

Surge Protection Zener Diodes are electronic components designed to protect circuits from voltage spikes by clamping excess voltage to a safe level. These diodes are especially critical in ...

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 ...

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 ...
