3EZ75D5E3/TR8 Application Field and Working Principle

The 3EZ75D5E3/TR8 is a Zener Diode that is specially designed for voltage regulation applications. It is a low power, single cathode Zener diode that operates from a supply voltage of between 5 and 65 volts. The diode has a maximum power dissipation rating of 500mW and is characterized by a series reactive voltage of 3.75V.

A Zener Diode is a special purpose device that is used to regulate the voltage in a circuit. In its forward-biased state, it behaves like a normal diode, but when the voltage across it becomes larger than the Zener voltage, the diode starts to conduct in the opposite direction. This current, called a Zener current, is able to control the voltage at the diode terminal, therefore ensuring a low voltage output even if the input voltage is above the Zener voltage.

In order to understand the working principle of the 3EZ75D5E3/TR8, it is necessary to first understand the basic structure of a Zener diode. A Zener diode consists of two regions called the P-region and the N-region. The P-region is the anode and the N-region is the cathode. In normal operation, a small current flows from the anode to the cathode, keeping the diode reverse biased. When the voltage across the diode becomes bigger than the Zener voltage, the N-region will start to conduct, allowing a large current to flow from the cathode to the anode. This current is the Zener current and is responsible for keeping the voltage across the diode constant, even if the input voltage is higher than the Zener voltage.

The 3EZ75D5E3/TR8 is specially designed for voltage regulation applications, and its characteristics make it particularly suited for this purpose. The series reactive voltage of 3.75V ensures that the voltage across the diode remains constant, even if the input voltage increases above the Zener voltage. The low power dissipation rating of 500mW ensures that the diode will not be damaged by excessive current flowing through it. Finally, the low operating voltage range of 5 to 65 volts makes it suitable for use in a wide range of applications.

In summary, the 3EZ75D5E3/TR8 is a low power, single cathode Zener diode that is specially designed for use in voltage regulation applications. It has a series reactive voltage of 3.75V, a maximum power dissipation rating of 500mW, and a low operating voltage range of 5 to 65 volts. The diode is capable of controlling the voltage across itself, even if the input voltage is higher than the Zener voltage. This makes it an ideal choice for applications where a low, stable voltage is required.
