Varistors are powered electrical electronics that provide surge protection to a variety of electrical systems. A varistor is a two-terminal passive semiconductor device that works like a voltage-sensitive resistor. Commonly referred to as one of the most common surge protection components, varistors are found in a variety of different applications. The USB0002DP application field and working principle is an especially important one, as it is the first ever use of this technology in USBs.

Varistors are devices used to protect electrical systems from transient overvoltages that occur in most circuits. Whenever a surge increases in voltage, the varistor will restrict the flow of electricity, thus limiting the current traveling through the circuit and protecting the system. The USB0002DP varistor is a bimetal film varistor with dual zinc oxide (ZnO) placed on a single ceramic substrate with a printed silver electrode in the middle. This is a small and robust protector which is designed to protect USB data lines from electrical transients. It works by clamping the voltage between two data lines. When the current exceeds a certain level the USB0002DP will limit the voltage differences between the two data lines. This prevents any excessive current from damaging the USB data lines.

In terms of its applications, the USB0002DP is suitable for USB 2.0 port applications. It is also a cost-efficient and economical solution for those that need surge protection. Moreover, because this device can be installed very quickly, it is a time-saving choice for the installation of USB implementations.

In terms of the technology’s working principles, the USB0002DP features an integrated electrostatic discharge (ESD) protection circuit. This circuit is responsible for controlling the voltage and current between two data lines, and it does this by clamping the voltage between the two lines. When the current exceeds a certain limit, the ESD circuit will start limiting the voltage differences between the two data lines. This effectively protects the USB from any excessive currents. Additionally, the USB0002DP varistor also has built-in overvoltage protection (OVP) technology, which is designed to restrict the amount of voltage that can pass through it when it is used for surge protection.

In summary, USB0002DP varistor is an ideal solution for those who need surge protection for their USB implementations. It is a cost-efficient and economical solution that is quick and easy to install. Furthermore, it provides an integrated ESD protection circuit as well as OVP protection, ensuring that a circuit can be protected from excessive and unwanted currents.
