TVS diodes are rapid acting transient voltage suppressors (TVS) devices designed to protect against electrostatic discharge (ESD), and are critical components for protecting sensitive circuits from lightning strikes, surges, and other extreme events. The TVS348 is a new type of TVS diode that stands out from other products in its class due to its low forward voltage drop, fast response time, and high relatively high current ratings.

Due to its inherent performance characteristics, the TVS348 is an ideal choice when it comes to protecting electronic circuits from voltage transients. It is commonly used in a wide range of applications, including automotive systems, telecommunications, consumer electronics, industry automation, and industrial control systems.

The TVS348’s functionality is based on its ability to perform two functions simultaneously when subjected to a voltage transient. The first function is the production of a high voltage, short-duration spike that is absorbed by the diode. This allows the device to act as a transient absorber by dissipating the energy generated by the transient, thereby eliminating the potential damage that would otherwise be caused to the protected circuit.

The second function of the TVS348 is to prevent any further surge from passing through the protected circuit by providing a low impedance path to ground. This significantly reduces the magnitude of the surge current, thereby significantly reducing the risk of damage to the protected components.

The TVS348 is different from standard TVS diodes in that it incorporates a low forward voltage drop, typically in the range of 0.9 to 1.5 volts. This enables the device to provide more protection without introducing excessive voltage drop into the protected circuit. The device also has a fast response time, rated at 1-2 nanoseconds for the standard 10KV ESD protection specified in the UL standards.

The TVS348 also features a relatively high current rating, with peak pulse current ratings up to 11A. This makes it ideal for applications that require protection from high current surges, such as automotive electronics, which are often subjected to surges of up to 8-10A. Additionally, the TVS348 can also provide up to 17A of peak current protection when used in conjunction with other TVS assemblies.

Overall, the TVS348 is an ideal choice for protecting circuits from voltage transients due to its low forward voltage drop, fast response time, and high current ratings. This makes it suitable for use in a wide range of applications, including automotive electronics, consumer electronics, telecommunications, industrial automation, and industrial control systems.
