MMSZ4694-G3-18

Diodes - Zener - Single

The MMSZ4694-G3-18 is a single Zener diode, commonly used in applications requiring an adjustable electric current. It is a short-circuited diode, meaning that it automatically restricts current flow through the diode when it is biased in reverse. This form of diode can often be found in electrical control systems, such as in power supplies, where it is used to regulate the voltage.

A Zener diode consists of two pieces of semiconductor material, connected at one end and doped with a certain type of impurity. The doping level of the two semiconductors determines the electrical characteristics of the diode, including the voltage required to reverse bias the diode and the amount of current that can flow through it. The MMSZ4694-G3-18 is a diode that operates at 18 volts, meaning that when it is reverse biased, the voltage across it will be limited to 18 volts. This is beneficial in applications where a steady voltage is required, as this type of diode can protect components from excessively high voltages.

In addition to voltage regulation, the MMSZ4694-G3-18 can also be used to direct electric current in one direction while allowing current to flow in the opposite direction. In this mode, the diode can be used to protect components from excessive reverse current, preventing any damage due to over-discharge of power supplies or other components. The diode can also be used as a switch in logic circuits, where it acts as a gate to allow or deny the passage of current.

The MMSZ4694-G3-18 is a versatile diode, with applications in a wide range of electrical components and systems. It is popularly used in power supplies, voltage regulators, motor controls, logic circuits, and converters. Due to its low cost, high reliability, and small form factor, it is widely deployed in various consumer devices and applications, such as smartphones and tablets. Its versatility makes it a viable option for much of today\'s electrical systems.
