MMSZ4690-G3-18 is a single Zener diode which is a semiconductor electrical component with two terminals. It is typically used to prevent a voltage from increasing more than a set amount. It works by breaking down when a set reverse voltage, called the zener breakdown voltage, is reached.

MMSZ4690-G3-18 is primarily used in reverse-voltage protection circuits, voltage clamp circuits and voltage-switching circuits. It is usually available in a range of voltages between 5.1V and 10V, with MMSZ4690-G3-18 being rated for 9.1V. The major parameters for its characteristics include power dissipation, junction capacitance, and maximum operating temperature, etc.

The working principle of MMSZ4690-G3-18 is that when the applied reverse voltage increases, just above the zener breakdown voltage, the diode breaks down and conducts current. This current flowing through the diode causes a voltage drop across it, thereby protecting the circuit from any further increase in the applied voltage. It works as a shunt regulator in this application.

Due to its characteristics, MMSZ4690-G3-18 is used in many consumer electronics and other electrical devices. It can help control the voltage in circuits and is used to protect power supplies from over-voltage and surges. Its low power dissipation allows use in circuits that require a low current draw. It is also used in power protection circuit for microcontrollers and other digital logic devices. Other applications for the MMSZ4690-G3-18 include logic level thresholding, line regulation and frequency stabilisation.

MMSZ4690-G3-18 is a very reliable and efficient diode and is widely used in many applications. It is capable of withstanding large reverse voltages while still providing sufficient current to protect the circuit it is connected to. It is a quick and effective way of protecting a circuit from voltage surges and over-voltage while still allowing current flow.
