TVS, or Transient Voltage Suppressor Diodes, is a type of semiconductor designed to protect against over-voltage conditions, such as electrical or electrostatic transients, and high energy pulse transients. It is made of silicon carbide, a very hard and brittle material, and is most often combined with a fast acting thyristor or diode to achieve the desired protection. TVS diodes are used in a wide variety of applications, from telecommunications and electrical systems, to consumer electronics.

In electronics, a TVS diode\'s job is to protect devices from transient transients. Transient transients may cause interference in circuits or be high-voltage pulses that can damage components. TVS diodes provide protection by quickly, accurately and cost-effectively absorbing and safely dissipating excess destructive electrical energy. TVS diodes minimize the risk of damage to sensitive components.

A TVS diode can be used in a wide variety of applications such as LED lighting, automotive systems, consumer electronics, telecommunications, power distribution and industrial applications. They are also used to protect sensitive electronics from high voltages and surges caused by lightning strikes, power fluctuations and electrostatic discharge. TVS diodes can also be used to protect from inductive load transients. In a nutshell, they protect against transient voltages by providing a clamping voltage above the rated voltage.

Although the mechanism of action of TVS diodes is different from that of other transient suppression devices, their basic function is the same: they reduce the peak voltage of transient pulses. This is accomplished by absorbing the energy from the transient pulse and dissipating it as heat. The diode limits the voltage on the device it is protecting to below its breakdown voltage.

A typical TVS diode consists of a PN junction. When a voltage is applied in the reverse direction, the diode begins to conduct, and it eliminates the transient by clamping the applied voltage to a safe level. These diodes have a low voltage breakdown, usually between -25 and +25 V, and a maximum reverse pulse current rating of up to 1000 A. A TVS diode\'s working voltage depends on the type, size and material composition of the diode.

When a TVS diode is used to protect a circuit, it is connected across the circuit with its anode connected to the power supply and its cathode connected to the circuit. During a transient event, the TVS diode will conduct sufficient current to clap the applied voltage, thus protecting the circuit from damage. By doing so, the diode also dissipates the transient energy as heat.

TVS diodes are widely used in a wide variety of applications, due to their small size, low power consumption and fast reaction time. They are robust, reliable and easy to install, and are available in a wide variety of sizes, ratings and types. As such, they are an essential part of many modern electronic systems.
