MMSZ4699-G3-18

The MMSZ4699-G3-18 is a single Zener diode from the 3.2 V to 75 V family, offered in the SOD-123 package. It features a low leakage current and low thermal resistance. This diode is designed for applications in LED lighting, regulators, switching power supply, linear power supply, and automotive.

MMSZ4699-G3-18 has a working principle that involves the flow of electron between the two terminals called anode and cathode. When the circuit is open, the electrons travel in a straight line through the diode, while when the circuit is closed, they travel at an angle, due to the built-in electric field in the diode\'s substrate. This creates an adjustable voltage gradient between the two terminals, which is what allows the diode to perform Zener breakdown, which limits the voltage across it.

The main application area of the MMSZ4699-G3-18 diode is in LED lighting, where it is used to regulate current flow. The diode can also be used in regulators to limit overvoltage and reduce the risk of damage to electrical components. Additionally, its small package size makes it suitable for use in automotive circuitry, providing reliable voltage regulation. Finally, the diode can be used in both linear and switch power supplies, providing efficient current regulation.

In summary, the MMSZ4699-G3-18 is a single Zener diode that is most commonly used in LED lighting and various other applications. It works by controlling the flow of electrons between its two terminals, creating an adjustable voltage gradient. This allows the diode to function as a voltage regulator, protection against overvoltage, and current regulator.
