Introduction

The V20P17AUTO is a family of high-performance varistors which is designed for use in Automotive applications. Varistors are electronic components that can be used in single-phase and three-phase circuits to prevent surge voltages from entering the system. They operate by dissipating the surge energy to ground instead of allowing it to enter other, more sensitive, components of the system. This can prevent damage to other components andprotect the system.

Features & Benefits

The V20P17AUTO is designed for use in Automotive applications due to its high performance and low leakage characteristics. It offers protection against transient surges up to20kV and also features an operating temperature of -40°C to +125°C. Its low leakage current and wide operating temperature range make it ideal for use in cars, trucks, and other automotive applications. Additionally, the V20P17AUTO features a low capacitance value, which helps minimize noise over the entire operating temperature range.

Applications

The V20P17AUTO is suitable for a wide range of Automotive applications. This includes engine control systems, ABS systems, transmission control systems, and fuel injection systems. It can also be used in systems where the potential for transient surges is relatively high, such as Ignition systems and Airbag systems. Additionally, the V20P17AUTO is suitable for use in electric race cars, hybrid cars, and alternative fuel vehicles.

Working Principle

The V20P17AUTO is a nonlinear, two-terminal device that operates on the principle of the P-N junction diode. When a surge voltage is applied across the device, a large current is injected into the junction that reduces the potential barrier between the semiconductor material in the junction. This allows the current to flow freely, thereby dissipating the surge energy into the ground.The V20P17AUTO also features a variety of protection mechanisms that can be used in Automotive applications. For example, it has a built-in reverse conductivity protection feature that prevents damage to other components by shutting off the current if the surge voltage tries to flow in the opposite direction. It also has an EP protection feature that prevents damage to the semiconductor junction if the surge voltage is too high.

Conclusion

The V20P17AUTO is a high-performance varistor designed for use in Automotive applications. It features a wide range of features and benefits, including a high surge voltage rating, low leakage current values, and wide operating temperature range. Additionally, it offers a variety of protection mechanisms that can help protect the system from damage caused by transient surges. The V20P17AUTO is suitable for a wide range of Automotive applications, including engine control systems, ABS systems, and fuel injection systems.
