TVS (Transient Voltage Suppressor) diode, MOV (Metal Oxide Varistor), and varistor are three components that work together to provide overvoltage protection in automotive, avionics, and industrial applications. This article explains the application fields and working principle of the VE13P01750KED component, which is a type of Varistor.

Varistors are non-linear voltage-dependent resistors requiring a power source to provide the necessary current to function. These components are made up of transition metal oxides, such as zinc oxide or cobalt oxide, and are designed to clamp voltages above a specified threshold value. They have a wide operating frequency range and can handle surge currents up to 2,500 amperes in a single cycle. Varistors can be used for EMI (Electromagnetic Interference) protection, as a surge limiter, and in ESD (Electrostatic Discharge) circuits. VE13P01750KED is a type of varistor used in automotive, avionic, and industrial applications.

The VE13P01750KED has a reverse voltage of 13V and a peak surge voltage of 175V. Its thermally triggered current rating is 3A, with a maximum voltage of 8V at 25 °C. This component can dissipate up to 650 mW of power when connected in series with an appropriate resistor. Additionally, VE13P01750KED has a fast response time of less than 200 ns and a low clamping coefficient for improved switching performance in surge applications. It is also capable of working with low impedance sources and can operate in temperatures ranging from -40°C to 85°C.

The working principle of VE13P01750KED is quite simple. When an overvoltage is applied, the metal oxide varistor material increases its resistance. This increases the voltage across the component and limits the overcurrent. When the applied voltage returns to the normal range, the resistance of the component decreases and it returns to its original state. Thus, the circuit is protected from the effects of overvoltages while the metal oxide varistor dissipates the excess energy.

VE13P01750KED components are used in a wide range of applications, including automotive, avionics, and industrial applications. In automotive applications, they are mainly used to protect electric circuits from random voltage surges. They are also used in avionics and industrial applications to provide EMI and ESD protection to sensitive components from electromagnetic disturbances. Additionally, they can be used in consumer electronics to provide surge protection and circuit protection in high-frequency applications.

In conclusion, VE13P01750KED is a type of varistor designed for automotive, avionic, and industrial applications. This component has a wide operating frequency range and is capable of handling surge currents up to 2,500 amperes. It has a reverse voltage of 13V and a peak surge voltage of 175V. Furthermore, its thermally triggered current rating is 3A, with a maximum voltage of 8V at 25 °C. It has a fast response time of less than 200 ns and a low clamping coefficient for improved switching performance in surge applications. The working principle of varistors is based on the voltage-dependent resistance of the metal oxide material, which increases under overvoltage conditions and decreases when the applied voltage returns to the normal range, providing overvoltage protection.
