TVS - diodes, or Transient Voltage Suppressors (TVSs) are one of the most crucial and essential components that is necessary in any electronic system. This is because of their ability to limit surges of electrical power and other transient disturbances across the circuit, which can cause the system to malfunction even if they are slight. The AOZ8806DI-05, which is one type of TVS, can fit, in particular, a variety of applications.

Application Field:

The AOZ8806DI-05 was designed and created to serve an Electronics Load Switch, which is like the switch that will control the power supply of the electronic system. In systems that need a minimum current for the switching to turn on, the AOZ8806DI-05 can serve as the low capacitance device that will ensure the stability of the current turn-on. Other applications that the AOZ8806DI-05 can be utilized for are protecting electric ICs against high-frequency (HF) noise, or there can be a time delay switch used in the system where the AOZ8806DI-05 serves as a buffer.

Working Principle:

The AOZ8806DI-05’s working principle is very straightforward and based on the bi-directional TVS, also known as a Diode TVS. To be more specifically, the device holds a unidirectional TVS configuration, and two TVSs are connected in antiparallel and placed on the top and bottom of the PCB layout. This is a nonlinear form of impedance that acts as an overvoltage protection device used in a variety of digital protection circuits, protecting the IC, power supply, and other components from surges, shocks, and other transient disturbances.

When the AOZ8806DI-05’s limit current, which is about 13A peak and 6A continuous, is exceeded, the device begins to conduct. Here, the two diodes begin to act as a single device, and a short circuit pathway is thus created between the power supply and ground. If the transient was high-energy related, the device will be destroyed in the process, and this protects the system components from the spike, preventing any possible malfunction.

In addition, the AOZ8806DI-05 offers other advantages that are worth noting. This includes its ability to suppress transients of any polarity, regardless of their high-frequency content. It also covers broad ranges of energy from hundreds of watts to few watts. This is combined with a very low clamping voltage, which typically ranges between 8 and 15 volts, and is why it is highly suitable for working with low voltage systems.

Conclusion:

The AOZ8806DI-05 is a great example of an effective and reliable TVS, and is suitable for a number of different applications ranging from delayed switching, protection of ICs from high-frequency noise, and low capacitance switching. Its working principle is also simple and efficient, making it easy to use and reliable for its purpose.
