A zener diode is very useful when you have a load that needs a steady voltage. A zener diode is a special type of diode that lies at the heart of voltage regulators and circuits generating the reference voltage for a differential amplifier. Adalm2000 Zener Diode Regulator Analog Devices Basics Introduction To Zener Diodes Evil Mad Scientist Zener Diode Basic Operation And Applications The usp of a zener diode is that it conducts current in both directions but what is so unique or special about that. How zener diode works as regulator . This makes it possible to use a zener diode as a constant voltage device or a voltage regulator. When a resistor zener chain is used as a regulator the maximum and minimum current draw from the load needs to be taken into account. A zener diode has a relatively steep voltage to current curve in the reverse bias mode at its rev...
