Varistors, or voltage-dependent resistors, are used in all types of electronic circuits to protect components from overvoltage spikes. Many electronic components such as transistors, diodes, and integrated circuits require protection from voltage swings in excess of their rated parameters. Varistors are one of the most commonly used forms of voltage protection.

VE17P00151KED is a part of a family of solid state varistors typically manufactured as an axial leaded package component. It is used as a voltage-dependent resistor in small to mid-sized electronics applications. This particular part has a capacitance of 150pF and an operating voltage range of 6V to 17V. Its primary function is to protect sensitive components from voltage spikes or transients that may occur during operation.

The working principle of VE17P00151KED is based on the fact that a varistor’s resistance decreases as the voltage increases. It is essentially a resistor that diminishes in resistance as the applied voltage increases, granting a form of short-duration protection, especially when such surges are caused by lightning or other large electrical disturbances.

The body of the device is made of zinc oxide, an electro-conductive material. This material behaves like a controlled semiconductor, meaning that at a specific voltage threshold, the material switches between a low and high resistance state. The change in resistance is what serves to protect the circuit components from over-voltage.

The operating voltage of VE17P00151KED defines the threshold voltage at which the device will begin to conduct current. For a given operating voltage, if the applied voltage is less than the threshold voltage, the device will behave as an open circuit. If the voltage is higher than the operating voltage, the device will behave as a low resistance path. The resistance of the device will decrease in relation to the amount of applied voltage. This is known as clamping and the device is acting as a clamp, or better known as a “clamper”.

VE17P00151KED is used in a wide variety of applications. It can be found protecting sensitive components in consumer electronics, automotive applications, audio systems, telecom equipment, and much more. Due to its low cost, reliability and ease of use, it is one of the most popular forms of short-term overvoltage protection available on the market today.
