Application Field of 3EZ82D/TR8

The 3EZ82D/TR8 can be used in a wide range of applications. It is typically used for voltage regulation, voltage sharing, and voltage reference. In voltage regulation applications, it is used to stabilize voltages in power supplies, voltage dividers, and other circuits. In voltage sharing applications, it is used to equalize the voltages between multiple power supplies. And in voltage reference applications, it is used to provide a constant voltage reference in circuits such as voltage regulators and voltage-controlled oscillators.

Working Principle of 3EZ82D/TR8

The 3EZ82D/TR8 works by utilizing the Zener breakdown effect. In this effect, a diode is reverse biased. This causes an electric field to build up in the diode structure. When this electric field surpasses a certain value, known as the breakdown voltage, the diode allows current to flow in reverse, preventing further buildup of electric field. The 3EZ82D/TR8 contains two different Zener junctions in a single package. The two junctions are connected in parallel and are used to control and balance the voltages in the circuit. When the input voltage rises above the breakdown voltage of the lower junction, current flows through the upper junction, thus balancing the voltages between the two. The breakdown voltage and the device capacitance ratios of the 3EZ82D/TR8 can be pre-set according to the required application. The device can also be operated at varying temperatures, making it suitable for high temperature applications.

Conclusion

The 3EZ82D/TR8 is a member of the Zener Single family. It is typically used for various electrical applications including voltage regulation, voltage sharing, and voltage referencing. The device works by utilizing the Zener breakdown effect, with two junctions connected in parallel to allow for the voltages to be balanced. The 3EZ82D/TR8 is available in several packages and can operate at temperatures of up to 500V. This makes it a versatile solution for a variety of applications.
