TVS - Diodes are an important piece of technology that has been used to help protect electrical components, devices and vital hardware from the effects of electrical overstress (EOS) or electrical overvoltage (EOS) damage. The S2ZMMBZ18VALT1G is a particularly popular type of diode and is widely used for protecting electronic components from electrical overvoltage transients. In this article, we will look at the application field and working principles of the S2ZMMBZ18VALT1G in greater detail.

The S2ZMMBZ18VALT1G is designed to help protect against EOS damage caused by electrical transients, surges, and spikes. It is one of the most commonly used devices for protecting electrostatic discharge, lightning, and other voltage transients from damaging sensitive electronics and hardware. It is a double-ended, dual-channel transient voltage suppressor diode that provides significant clamping protection and can withstand up to 18 volts in Vmax.

The S2ZMMBZ18VALT1G has a wide range of applications, including automotive electronics, robotics, industrial machines, wearable tech, and medical devices. It is commonly used to protect entire systems such as medical cutting tools and robots. Also, in the automotive industry, it is applied to protect sensors and other electrical circuits from electrical transients. The diode works by limiting the rate of current through the device by clamping excessive voltage and reducing power loss.

The S2ZMMBZ18VALT1G works by combining a zener diode with a transistor to provide overvoltage protection by clamping the transient voltage. The diode works by providing a low impedance path to ground which serves to protect the components by diverting the voltage to the ground or supply rail. This way the output signal remains intact, unaffected by the transient voltage.

In addition, the TVS diode also includes photodiode protection which helps protect against overvoltage transient spikes and surges. The photodiode senses any increase in voltage and rapidly reacts by reducing the current flow. This helps to protect from sudden spikes that could otherwise lead to damage of the components.

The S2ZMMBZ18VALT1G is equipped with a built-in thermally-activated fuse that provides over-temperature protection. This fuse provides additional protection against thermal stress caused by high voltage and high current requirements. This makes it an excellent choice for many applications that require high voltage protection.

Overall, the S2ZMMBZ18VALT1G is a versatile diode that is effective in clamping transient voltage and reliable in overvoltage protection. Its wide range of applications makes it an ideal choice for a variety of projects, from automotive electronics to robotics. Its combination of a zener diode with a transistor provides optimal protection and makes it an excellent choice for protecting electronics against electrical transients.
