The V481DB40 is a highly efficient Transient Voltage Suppressor (TVS) manufactured by Vicor, widely used in electronic devices as a protected environment from transient voltage events. It is also a member of the Varistors, Metal Oxide Varistors (MOV), and Transient Voltage Suppressor (TVS) products, which are three different types of protective devices for preventing overvoltage or high voltage from damaging vulnerable electronic components or systems. The V481DB40 is primarily designed as a bidirectional ESD clamp to protect the nodes of a high speed data line from electromagnetic interference (EMI) or electromagnetic pulse noise (EMP) disturbances. In addition to providing excellent protection against these types of event, the V481DB40 also offers excellent EMI noise attenuation, making it an ideal choice for applications that require a low-loss signal path for high speed communication. The core working principle behind the V481DB40 Transient Voltage Suppressor is its ability to detect and shorts high voltage by utilizing the nonlinear characteristics of the Varistor. The Varistor is a voltage-dependent resistor made from Zinc Oxide and other mixed elements, which exhibits highly nonlinear and bidirectional resistance characteristics with respect to applied voltage. When connected across a signal line, the V481DB40 will detect both transient disturbances and reverse-biased leakage current. When the voltage across the Varistor exceeds the device’s clamping voltage, it will then clamp the voltage to a safe level and thus providing an eye-safe level of protection against these types of events.The V481DB40 has a wide range of applications. It can be used to protect computer systems, telecommunications equipment, digital control systems, and other circuit designs. Additionally, when deployed in Semiconductor Processor Power boards and backplanes, it can effectively reduce electro-magnetic interference and protect delicate circuits. It is also well-suited for use in automotive applications, where it can protect on-board systems from power related issues due to the effects of surge and electromagnetic interference. The V481DB40 is an extremely useful device in a wide array of electronic products and systems. It is a cost-effective and efficient solution for protecting circuits from transient voltage events and other types of power disturbances. With its bidirectional technology, excellent EMI noise attenuation, and ESD protection, the V481DB40 provides reliable protection for sensitive electronic components and systems.
