The circuit presented here is compact and handy for measuring the voltage rating of a Zener diode instantly. To check a Zener diode, it is connected across a DC power supply with a suitable resistor ...

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 ...

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...

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 ...

The power supply in your computer manages all of the power required to run each component of your computer. When this critical component begins to fail, your computer may power off unexpectedly, ...

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 ...
