TVS - Diodes

A transient voltage suppressor (TVS) diode is an electronic component that is used to protect sensitive circuits from voltage spikes, often caused by sudden voltage surges. TVS diodes are commonly used in a wide range of applications, such as communication systems, power supplies, automotive and industrial circuits, and consumer electronics.

The JANTX1N6118A is a type of TVS diode, specifically designed for high-power protection applications. It is constructed with an insulated-gate bipolar transistor (IGBT) and a MOSFET in a 4-pin package. This diode features a surge protection capability up to 3.0 kA, very low capacitance of 6 pF typ, and fast response time of 200 mA in 10 nanoseconds.

The JANTX1N6118A is ideally suited for a variety of application areas. These include power factor correction, voltage regulation, over-voltage protection, surge protection, and transient voltage suppression. It is also commonly used in automotive and aerospace applications.

Working Principle

The JANTX1N6118A is designed to protect sensitive circuits from excessive voltage. When supplied with an overvoltage, it provides a low impedance path for the current that is directly proportional to the voltage. As the voltage across the diode increases, the current in the diode increases as well. This current can be dissipated away by the power supply, protecting the circuit from damage.

In addition, the JANTX1N6118A features a low capacitance and fast response time, making it well suited for use in high speed applications, such as transmission lines and data storage devices. The fast response time allows the JANTX1N6118A to quickly clamp overvoltages and protect the circuit, as it limits the amount of energy that can be transferred.

The JANTX1N6118A also has a high surge current capacity, allowing it to handle large voltage spikes. This is especially important in applications where lightning and other large transient voltages are present.

Overall, the JANTX1N6118A is an excellent choice for a wide range of applications requiring overvoltage protection. It features a fast response time and a high surge current capacity, making it ideal for protection against high voltage transients. Its low capacitance also makes it well suited for high speed applications.
