TND05V-390KB00AAA0

TVS (Transient Voltage Suppressors) - Varistors, MOVs (Metal Oxide Varistors), are commonly used in power electronics, and in recent years, other applications have also emerged. TND05V-390KB00AAA0 is a Silicon Avalanche Diode (SAD) varistor from a leading electronic component manufacturer, designed for protecting against lightning, transients, and other voltage surge events. It offers low leakage current, fast-acting protection, and excellent clamping efficiency.

SAD varistors are made up of a silicon layer, with a pair of symmetrical plates on top and bottom which contain several metal oxide layers. When an overvoltage occurs, the Si layer charges quickly, creating an avalanche breakdown and thus producing a low impedance path for the current. In this way, it acts as a clamp, diverting the excess voltage away from the electrical components and allowing the rest of the circuitry to remain unaffected.

The TND05V-390KB00AAA0 is ideal for protecting electronic equipment against lightning, inductive switching surge, and electrostatic discharge (ESD) with its operating voltage range of 5.5 to 390V. As it uses an SAD structure, it has superior transient protection and very low capacitance. Its excellent clamping capability makes it suitable for lightning protection applications, while its low leakage current of less than 1µA assures low power dissipation and preserves power integrity.

In addition to lightning protection, the TND05V-390KB00AAA0 is also suitable for a variety of other applications, such as ESD protection, line card protection, overvoltage protection, and voltage regulation. It is commonly used in power supplies, DC/DC converters, motor controllers, inverters, and consumer electronics, as well as automotive, medical and industrial applications.

Overall, the TND05V-390KB00AAA0 SAD varistor combines fast-acting transient protection with superior clamping capability to ensure reliable operation of electronic equipment in a wide range of applications. It is a highly efficient varistor, and its excellent performance in surge and ESD protection makes it the perfect choice for power electronics.
