TVS (Transient Voltage Suppressor) devices such as Varistors, MOVs (Metal Oxide Varistors) and diode arrays are essential devices used in a wide range of electronic products to help protect them from transients such as Electrostatic Discharge (ESD) or Transients generated from external sources, like lightning or power surges.

In this article, we will discuss the application field and working principle of V20E175PL2T, one of the most popular devices in the Varistor family.

Application Field of V20E175PL2T

V20E175PL2T is a surface mount device designed to protect high-speed data lines, allowing a DC overvoltage protection of 17.5V. It has a Leakage Current of 150mA or less and has a Fast Response Time of <=10ns. It also has a high Voltage Breakdown, making it well suited for protecting sensitive electronics from electrical transients.

The V20E175PL2T can be used in a wide array of applications, such as protecting unprotected data ports, automotive electronics, portable electronics, computers, communication systems, and more. It is available in a variety of packages to suit the application, including 0402, 0603, 0805, 1206, 1210, and 1812 packages.

Working Principle of V20E175PL2T

The V20E175PL2T works by utilizing a Zinc-Oxide varistor element. The Varistor has two opposite electrodes made of zinc oxide particles, and a special conductive elastomer which acts as an electrolyte between these two electrodes. When subjected to a voltage, the particles form an electric field, and current begins to flow through the device. The current flow is dependant on the resistance of the material and the applied voltage. When a residual voltage from external sources, such as ESD or power surges, is applied, the voltage across the varistor increases. When the applied voltage is beyond the specified breakdown voltage, the resistor will break down and absorb the energy from the transient.

The V20E175PL2T is a uni-directional device, meaning it can only dissipate energy in one direction. This can be beneficial in applications where the voltage from the transient source is low in comparison to the local ground voltage. In such applications, the V20E175PL2T can help to protect the component by diverting the energy from the short circuit.

Conclusion

V20E175PL2T is an advanced surface mount Varistor device which is designed to protect sensitive electronics from transients such as ESD or power surges. With its high Voltage Breakdown and Fast Response Time, the V20E175PL2T is well suited for a variety of applications, such as protecting unprotected data ports, automotive electronics, portable electronics, computers, communication systems, and more. The device works by utilizing a Zinc-Oxide varistor element for efficient absorption of transient energy, providing a reliable protection solution to your electronic devices.
