They are also used in feedback circuits to ensure that the output voltage of an amplifier remains constant even when the input voltage changes. MMBZ5256C-HE3-08 diodes can also be used in switched-mode power supplies and other circuits which need a stable power supply.

Working Principle of Zener Diodes

Zener diodes are special types of diodes which allow current to flow in either direction when the voltage is greater than a certain threshold, known as the Zener voltage. Zener diodes are made from heavily doped semiconductor materials which can withstand large voltage values without breaking down.When the voltage across a Zener diode is below the Zener voltage, it behaves like any other regular diode and blocks the current. When the voltage is equal to or greater than the Zener voltage, the diode starts to conduct current. This current is known as the Zener current.In some applications, the Zener diode is used as a voltage regulator. When the input voltage increases, the Zener diode reacts by conducting more current, thus preventing the output voltage from exceeding the Zener voltage. This makes the Zener diode an ideal component for stabilising circuits.
