Diodes – Zener – Single is a type of p-n junction diode working under reverse bias. Anode is the p-type side, whereas cathode is the n-type side. With the purpose of understanding and analyzing 2EZ47D5/TR8 application field and working principle, some basic theories in electrical and semiconductor engineering should be taken into consideration.

Polarization is always the foundation of a p-n junction and the primary key of controlling a diode behavior. A diode\'s conduction mainly relies on the size of voltage applied across it. In general, the current only begins to flow when voltage crosses the diode\'s threshold value and reaches a certain adequate level. Fortunately, due to the varying characteristics in semiconductor materials and doping intensities, manufacturers are capable of constructing different kinds of special diodes that are mobile and suitable in harsh environments.

Zener diodes are also part of the wider category of diodes orientated for protection, voltage control and bias applications. They are mainly used for voltage regulation and for protection against reverse voltage spikes in industrial and automotive applications. According to the conduction region, we have breakdown diodes, Zener diodes, avalanche diodes and others.

2EZ47D5/TR8 is a particular type of switching diode which has been manufactured by various worldwide semiconductor manufacturers. It is a single, medium power Zener diode, made of 6.96V Zener voltage and 5W power dissipation rate. It also includes a built-in strain relief to enhance terminal strength. It has a variety of uses including clamping, switching applications and voltage stabilization.

Diodes are conductors, they protect components by reducing the effects of a shock wave, allowing a surge of power to pass through it quickly. They are useful in limiting the voltage applied across a load to a stable voltage by providing an alternate low resistance path when the voltage applied across it exceeds the breakdown voltage.

In regards to the working principle of 2EZ47D5/TR8, we first have to understand the working principle of a normal diode. The diode is made up of a pn junction which when it is forward biased allows current to pass from the anode to the cathode. When the voltage applied is reversed, the diode does not allow current to flow, this is known as the reverse bias mode. However, unexpected breakdowns may occur when a reverse biased diode is exposed to a very high electric field. These breakdowns are triggered due to a decrease in the voltage threshold, thus allowing current to start flowing across the pn junction (reverse bias) even at a low voltage.

For the Zener diode, this special feature is taken advantage of, instead of a diode blocking reverse current. During the breakdown, the diode is set to a breakdown voltage known as the Zener voltage. The range of 1.2V to 200V is available in standard products. When a reverse voltage is applied across it, the diode starts conducting only if the voltage reaches the breakdown voltage, beyond which the current is limited by the Zener resistance (Rz). It is this situation where the Zener diode would behave as a voltage regulator.

As for 2EZ47D5/TR8, it is likely to be used in an AC-DC power supply circuit. Adding a capacitor before the diode and a resistor after the diode, this diode can create a stabilized output voltage of 6.96V from the main AC line. This 6.96V regulated DC voltage can also be used for powering DC devices.

Applications of 2EZ47D5/TR8 can be seen in numerous industries, including industrial automation, automotive, consumer products and power supplies. It can serve as a voltage regulator, an output voltage reference in circuits, a clipper and a clamper when it connects with other semiconductor components.

In conclusion, 2EZ47D5/TR8 is an ultra-low voltage Zener diode used to regulator the output voltage internally, no matter how many fluctuations the input voltage goes through. Its applications include industrial automation, automotive, consumer products and power supplies. It should be noted that these are only a few of the potential applications, as the device has a broad range of uses.
