V150ZU20PX10

TVS - Varistors, MOVs, are some of the most widely used transient voltage surge suppression (TVSS) components. Varistors, or transients, are voltage-controlled, non-linear devices that are designed to provide electrical protection. When the applied voltage exceeds a preset level, the varistor engages and redirects the electrical current away from the protected circuit. This prevents damage to the protected circuit from transient overloads.

The V150ZU20PX10 is a varistor series device manufactured by Vishay Draloric. It is a single-piece monolithic varistor designed for high surge protection levels. The two main parameters that define a varistor, its maximum operating voltage (V_max) and its current rating (I_imp) identify any particular varistor.

The particular model of the V150ZU20PX10 have a rated voltage of 150VRMS, and the capacitance from 0.45pF to 0.75pF. Minimum Insulation Resistance (R_ins) of the device is 100000MΩ min., and the peak pulse current (I_PP) is 70A. The energy which the device can absorb is 110J.

The V150ZU20PX10 is widely used in different applications thanks to its design and features. These include a key feature of having low capacitance, which is a very important performance criterion for applications with high frequency. Moreover, the device can handle high surge energy, reducing the component count and size of the circuit. It is compatible with high-speed, high-maintenance solid-state circuits, providing low leakage current.

The working principle of the V150Zu20PX10 is relatively simple. When its terminals receive a voltage higher than its maximum operating voltage, which is 150VRMS in this case, electrons are allowed to flow from its negative terminal towards the positive terminal. This forms an electrical loop which protects the protected circuit. During this process, excess energy is absorbed, dissipated and converted into heat.

In conclusion, the V150ZU20PX10 varistor model is one of the top TVS - Varistors, MOVs, in the market. It has an extremely high surge energy rating, high insulation resistance and low capacitance. Its high energy rating and low capacitance make it ideal for use in high-frequency, high-maintenance circuits. Finally, the varistor’s working principle is as simple as electrons flowing from its negative terminal, through the device, and out its positive terminal.
