TVS - Diodes, also known as Transient Voltage Suppressors (TVS\'s), are a type of protective circuit component that is designed to limit the levels of surges, spikes, and other forms of voltage transients seen in power and ground nodes of a printed circuit board. TVS diodes are typically used in high-reliability applications, such as automotive, military, aerospace, medical, and other high-voltage industrial applications, where electrical circuit overload protection is critical. The XGD10402KR is a TVS diode designed to offer electrical circuit protection with a low voltage and low capacitance values. This makes it suitable for protecting circuits from large surges, overvoltages, and other electrical transient events.

The XGD10402KR is a unidirectional TVS diode that has a Center Tap bidirectional configuration, meaning that it features two distinct output sections, each of which providing protection from surges in different directions. The XGD10402KR is capable of protecting two circuits in parallel, with each independent section providing protection from transients going in either direction. The device has a peak pulse voltage rating of 400V and a clamping voltage of 130V, with a very low capacitance of only 35pF. The low capacitance helps to ensure minimal signal integrity degradation when the device is in use. In addition, the XGD10402KR has a fast response time, with a typical activation time of only 60nS.

The XGD10402KR is an excellent choice for applications requiring high surge-protection capability with a low capacitance level. It is ideal for protecting sensitive circuits from large surges caused by lightning strikes or other sources of electrostatic discharge. Its low capacitance also helps to ensure that the surge protection does not degrade the signal integrity of the source circuit. The high voltage and low capacitance make the XGD10402KR ideal for applications such as automotive, medical, and military, as well as any other application requiring reliable surge protection.

The XGD10402KR works by encouraging current to flow away from sensitive components in the event of a power surge. In a surge situation, the current is diverted away from sensitive components by the non-conductive body of the XGD10402KR and into the parallel sections of the diode. This allows for current to be diverted safely away from the sensitive components, thus preventing damage. As the current is diverted away, the voltage across the XGD10402KR is clamped, at which point the current is no longer diverted.

In conclusion, the XGD10402KR is a high-quality TVS diode designed for a variety of surge protection applications. It features a low capacitance level and fast response time, making it ideal for use in high-reliability applications such as automotive, military, aerospace, and medical. The XGD10402KR has a maximum peak pulse voltage of 400V and a clamping voltage of 130V, and is capable of protecting two circuits in parallel. With its low capacitance, fast response time, and high surge-protection capability, the XGD10402KR is an excellent choice for any application requiring reliable surge protection.
