TVS or transient voltage suppressors are devices constructed using either diodes or specially designed circuits that use Zener diodes to protect against sudden voltage increases. TVS diodes are designed to conduct a high-current instantaneously in the event of a voltage surge. When there is a voltage surge, the high-current is usually short-lived, and the voltage returns back to its normal levels. This is where a TVS diode comes in; it can help protect sensitive electronics from a damaging voltage spike.

The MXSMCG36AE3 is a three-terminal unidirectional surface mount transient voltage suppressor (TVS) that provides overvoltage protection and ESD protection. It is a single-line diode array component designed for general purpose overvoltage and transient protection applications.

The MXSMCG36AE3 has an operating voltage of 36V and a peak pulse power of 3300W. With a low 6nS operating response time, it is designed for applications that require fast switching speed and fast recovery. This diode has a low on-state voltage of less than 3V and a low forward voltage drop of 0.37V which helps reduce power dissipation and enhance performance. The MXSMCG36AE3 is available in a small, lightweight 3-terminal SOT-23 package.

The MXSMCG36AE3 is designed for applications involving telecom, datacom, local area networks, etc. It is well-suited for applications involving ESD protection, electrostatic discharge protection, and overvoltage protection. It is also used for protecting voltage sensitive components against sudden voltage surges in systems such as motors, transformers, and generators.

The working principle of a TVS diodes is based on the principle of Zener breakdown. When the voltage across the junction of the diode exceeds the Zener voltage of the diode, it breaks down and allows current to flow across the junction. This breakdown phenomenon is called Zener breakdown or avalanche breakdown and it is used to protect sensitive components from sudden voltage spikes. When a voltage surge occurs, the TVS diode will conduct a high-current instantaneously and dissipate the excessive voltage.

When the voltage across the junction reaches its breakdown voltage level, current will start to flow through the TVS diode in the reverse direction. This current will be equal to the difference between the applied voltage across the junction and the breakdown voltage. The current will then be diverted to ground or the power supply, thus effectively clamping the voltage at the breakdown voltage level.

One of the main advantages of a TVS diode is that it can be used to protect sensitive components from voltage spikes with relatively low operating voltages. The MXSMCG36AE3 is designed for applications with operating voltages up to 36V, and can protect against voltage increases of up to 3300W. This diode also has a fast operating response time of 6nS, which makes it ideal for applications that require fast switching speeds and fast recovery.
