Here is a handy zener diode tester which tests zener diodes with breakdown voltages extending up to 120 volts. The main advantage of this circuit is that it works with a voltage as low as 6V DC and ...

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 ...

Suppose the zener diode on the circuit has a breakdown voltage of 10 V. What are the minimum and maximum zener currents? The applied voltage may vary from 20 to 40 V. Ideally, a zener diode acts like ...

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 ...

Abstract: Two temperature insensitive voltage reference types are widely used today, namely buried Zener and bandgap voltage. Reference voltages based on buried Zener diodes are less sensitive to ...
