Diodes - Zener - Single

The 3EZ82D2E3/TR8 is a zener diode that belongs to a single type device. A zener diode is a semiconductor device in which a heavily doped p-n junction is formed by establishing a highly resistive electrical junction between n-type and p-type materials in such a way that electricity can move through the junction when the applied voltage across it turns out to be very high.

When a zener diode is connected to an input power source, the circuit becomes complete and the current starts to move in the junction. As the resistance of the junction is very high, the current does not flow easily.

However, when the input power reaches a certain threshold level, the voltage across the diode increases and it starts to behave like a resistor instead of an open circuit. As the resistance of the diode decreases, the current starts to flow faster, creating a reverse bias current in the junction. This reverse bias current is responsible for passing the power from the input power source to the output power source.

The 3EZ82D2E3/TR8 zener diode operates at very low voltage and is used in many applications like voltage regulation, over-current protection and regeneration of power supply. It is also used in power amplifiers, power supplies and various circuits where an ultra-low current source needs to be regulated. It is also used in studio power amplifiers and audio switching amplifiers.

The working principle of the 3EZ82D2E3/TR8 Zener diode is very simple. When the applied voltage across the diode increases, the junction starts to behave like a resistor and the current starts to flow faster. As the applied voltage increases, the resistance of the diode decreases, thus increasing the current flow.

At this point, the reverse bias current starts to flow from the diode and helps in passing the power from the input power source to the output power source. As the circuits require ultra-low current sources, the 3EZ82D2E3/TR8 zener diode is used in these applications as it can provide the power without causing any extra current or voltage fluctuations in the system.
