Though field and working principle of 2803593 application are among the core components of Mixed Technology-TVS (Transient Voltage Suppression), what it is and why it is so important are yet to be discussed. TVS or Transient Voltage Suppression is an electrical component used to protect against voltage transients and it is highly applicable in providing power protection and system voltage stability.

A TVS is a diode-like device designed to absorb transient voltages, or short spikes, that can cause damage in electrical vehicles. It absorbs spikes in voltage above a rated level before sending the current safely to its destination. This is paramount in power supply designs for these vehicles, which can be damaged when a spike magnitude is too high. A large selection of TVS technologies, including dual-diode, triple diode, and high-speed solutions can provide the required levels of protection. To ensure optimal protection, TVS devices must be chosen with the exact voltage and current ratings. By absorbing these spikes in a timely manner, TVS devices help protect against damage.

As all electronics, TVS devices are sensitive to heat and their performance may reduce at higher temperatures. TVS are also susceptible to electrostatic discharge (ESD), with some level of protection determined by their voltage and current ratings as pointed out before. When designing circuits, engineers must consider the requirements of a particular system such as the maximum ESD levels, di/dt immunity, surge current, and power dissipation.

Although on the surface TVS appear the same, all devices are unique. Depending on their application, engineers need to understand the subtle differences between the various TVS designs and pick the one best suited for their power supply design. For instance, a TVS may be needed for I/O, control, or digital signaling. If the system is running at high current levels, then an oversizingTVS device may be needed to provide greater dispart protection. If the system is running on higher voltage, then the current rating must kept at a certain level for effective performance.

Mixed technology-TVS is an important component for providing power protection and system voltage stability in many applications. As mentioned before, all TVS devices have unique characteristics and capabilities that must be taken into account when designing power system circuits. Engineers must consider the requirement of the system, ESD levels, di/dt immunity, surge current, and power dissipation when selecting the appropriate TVS for their application. By selecting the optimum TVS device, engineers can ensure the system is efficiently protected from voltage transients.
