To measure a zener diode’s breakdown voltage, you need a dc voltage source whose voltage exceeds that of the zener voltage. In Figure 1, resistor R SER provides voltage drop between V IN and V ZEN. In ...

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 ...

In the world of electronics, a Zener diode stands out as an essential tool for regulating voltage and protecting circuits. But what makes it special? This guide is designed to break it down for you in ...

[Hans] wanted to see the frequency response of a bandpass filter but didn’t have a lot of test equipment. Using an RTL-SDR dongle, some software and a quickly made noise generator, he still managed to ...

Zener-Diode-as-Voltage-Regulator' This project demonstrates the use of a Zener diode as a voltage regulator to maintain a constant output voltage under varying input voltages (line regulation) and ...

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 ...
