TVS diodes provide essential overcurrent protection for a wide range of electronics. One such device is the 1.5KE400A-G, a Uni-directional Transient Voltage Suppressor (TVS) diode. It is designed to protect sensitive electronics from destructive voltage transients, most commonly induced by lightning, electrostatic discharge (ESD), and other electrical disturbances. The 1.5KE400A-G is one of the most frequently used TVS diode components because of its reliability, small size, and easy installation. The 1.5KE400A-G is designed with 500W peak pulse power (tpp) to absorb Damaged Induced Local Transients (DILTs), ESD, and lightning-induced transients. The device is composed of a two-terminal solid-state diode, with a blocking voltage of 400 V. This voltage defines the maximum acceptable voltage that can be supplied to the diode before it is damaged. The breakdown voltage after installation is 335V. Mechanically, the device measures 5.2mm x 11.3mm x 4mm. The diode, when used in applications, is able to yield overpressure protection up to 26 amps. The TVS diode is also RoHS compliant, offering an environmentally friendly solution for manufacturers.Common applications for the 1.5KE400A-G include industrial safety applications such as surge protection for telecom lines, safety circuits, and power lines. It is also used for consumer products such as LCD TVs, MP3 players, routers, and computer monitors.The 1.5KE400A-G device works by providing a fast response to overvoltage transients and switching surges. This protection is provided by a highly specialized semiconductor structure that behaves as a voltage-controlled switch in response to surges or transients. In this structure, a thin, heavily doped layer of silicon is placed between two thicker, less-doped regions. The two regions act as anode and cathode leads. When an overvoltage transient occurs, current flows through the heavily doped areas, and the thinner layer acts as a voltage-controlled switch, shutti- ing of the flow between the anode and cathode. The TVS endures multiple pulse-induced events without damage, and can be reset without physically being removed. When the stress event passes, the device reinstates the voltage drop across the diode, restoring the system to proper functionality.The 1.5KE400A-G offers numerous advantages for those who use it. The device is small enough to be integrated into very small electronic systems without taking up too much space. It is also highly reliable and offers excellent surge protection characteristics. Additionally, the device is cost-effective to manufacture, making it a popular choice for many industrial systems. Overall, the 1.5KE400A-G is a reliable and efficient device to protect electronics from ESD, DILTs, and lightning-induced transients. It offers desired features such as high tolerance to multiple pulse events, reliable operation, a small package size, and RoHS compliance. It is frequently used across many industries and consumer products, proving its versatility in various applications.
