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 ...

Figure 4 shows an assembled zener-diode-tester circuit. The zener diode under test is On Semiconductor ‘s BZX55C15RL, which has a working voltage of 13.8 to 15.6V.

Diodes whose reverse-breakdown characteristics are controlled precisely during manufacture are called as Zener diodes and are intended specifically for operation in the reverse breakdown mode ...

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.

Real-Life Applications of Zener Diodes The real-life applications of Zener diodes are extensive and varied. From voltage shifting in signal conversion processes to providing a stable voltage reference ...

The circuit is simple enough: it uses a capacitor, a resistor, and a pair of diodes (one of them a zener diode). He uses this basic circuit to drive simple regulators with input and output filter ...

Zener diodes can be downright baffling for beginners, especially when mistakenly thrown in a circuit in place of a regular 1N4001.
