The 3EZ75D5E3/TR12 is a single Zener diode designed to be used in a variety of applications. It was designed to provide a level of voltage regulation and protection, allowing current to flow in one direction while preventing any reverse current, and also to be able to withstand high temperatures and transient changes.

The 3EZ75D5E3/TR12 is designed with a nominal Zener voltage of 6.8V, with an allowable tolerance of ± 5%, and a maximum reverse current of 5mA. Its maximum power dissipation is at 300mW, with an operational temperature range of -65°C to 150°C, and Datasheet of the diode indicates a maximum thermal resistance of 125°C/W when mounted on a PC board. It also comes with an option for fast switchingapplication, through an available switch time of 10nS for less noise, and a better response in general.

The 3EZ75D5E3/TR12 is most commonly used in applications such as Zener voltage regulators, transient voltage protectors, and voltage reference devices. The Zener voltage regulator is designed to provide a constant output voltage regardless of input variations within its given range, allowing it to function as an effective protective device in circuits that are susceptible to voltage fluctuations. The transient voltage protector is designed to protect against transient voltage surges that may occur due to EMI (electromagnetic interference) or lightning, and it is often used for the protection of power circuits in a variety of applications. The voltage reference device is designed to be used with precision voltage measurements, ensuring a constant voltage to be used as a reference point in comparison to other, less precise measurements.

The working principle of the 3EZ75D5E3/TR12 is based on the principle of the Zener diode, in which a reverse potential gradient is set up across its junction. This potential gradient allows current to flow in one direction, while the presence of this potential at the junction prevents any potential backflow in the opposite direction. When the zener diode is forward biased, the voltage drop across it is very small, and thus it provides a low-resistance path for current flow. When it is reverse biased, and the voltage across it is greater than the Zener voltage, the junction becomes completely reverse biased and will not conduct any current in the reverse direction.

Finally, the 3EZ75D5E3/TR12 is an ideal solution for a variety of applications that require a reliable source of high-precision voltage regulation. Its ability to withstand high operating temperatures, its fast rise time and its wide range of Zener voltage tolerance make it an attractive choice for a variety of protective applications.
