1EZ200D/TR12 Application Field and Working Principle

The 1EZ200D/TR12 is a single Zener diode that provides stable voltage regulation. They are designed for both linear and switching power applications, and come in a variety of voltages, current levels and packages. The 1EZ200D/TR12 is ideal for on-board voltage regulation, due to its low power and low thermal resistance.

The 1EZ200D/TR12 is a type of diode, which is designed to conduct electricity in only one direction. Its electrical characteristics allow it to be used as a voltage regulator, and because of its low power requirements, it is suitable for many power supply applications. The 1EZ200D/TR12 is a Zener diode, meaning that it maintains a constant voltage across its terminals, regardless of the amount of current flowing through it.

In terms of applications, the 1EZ200D/TR12 is used to regulate the output of switching power supplies or DC-DC converters. It helps to ensure that the voltage of the output is exactly what is needed in order to power the connected device without overvoltage or undervoltage. It can also be used in linear power supplies, where it ensures that the voltage at the output remains consistent. The 1EZ200D/TR12 is also often used in automotive electronics and motor control circuits.

The working principle of the 1EZ200D/TR12 is based on the Zener breakdown effect. In a Zener diode, as the voltage across its terminals increases, the electric field increases too. At a certain point (called the Zener voltage), the electric field exceeds what is needed to break down the PN junction, causing the diode to conduct in reverse direction. This reverse breakdown current is controlled by the Zener diode\'s resistance, allowing it to keep the output voltage stable.

To summarize, the 1EZ200D/TR12 single Zener diode is used in both linear and switching power supplies to ensure a stable output voltage. This allows the device being powered to receive the exact voltage it requires without damage due to overvoltage or undervoltage. The 1EZ200D/TR12 is ideal for on-board voltage regulation due to its low power and low thermal resistance.
