V120ZC20PX10

The V120ZC20PX10 is a Varistor, also known as a Voltage Dependent Resistor (VDR), used to protect sensitive electronic equipment against electrical transient voltages. A Varistor is a non-linear device that acts as a clamping circuit to protect against electrical over-voltage. It is an economical and effective over-voltage protection solution that can be used in a wide variety of applications.

The V120ZC20PX10 has been designed with a peak pulse energy of 20J and is suitable for a wide operating voltage range of 250V to 1000V. It is also suitable for use in high-temperature applications, with a maximum temperature range of -55 to +125°C. This makes it well suited for use in industrial, automotive, and consumer applications.

The V120ZC20PX10 is a surface-mount device, with vented top and bottom connections, and is available in both leaded and leadless packages for different requirements. It is designed to provide superior surge protection at a peak current of 8kA for a 10/1000μs waveform. This device has a low leakage current while providing excellent protection against surge related events.

The working principle of the V120ZC20PX10 is based on the capacitive reactance provided by the device. When a surge occurs, the electrochemical properties of the VDR element will change, allowing the device to draw current away from the circuit. The capacitive reactance will also increase due to the high voltage, limiting the surge current, thus protecting the circuit.

The Varistor is designed to absorb transient and surge currents, dissipating them as heat and protecting the source of the load. Varistors are also well suited for ESD protection, absorbing Electro-Static Discharge and preventing it from damaging the protected component. In addition, Varistors are also common in Low Leakage current applications, providing a low, but effective, level of protection.

The V120ZC20PX10 Varistor can be used in many different applications, such as lighting, power supplies, industrial control systems, automotive electronics, and communications. It can be used to protect against surges, spikes, and overvoltage events, providing reliable and efficient overvoltage protection to downstream circuits. The V120ZC20PX10 also features a lower-than-average leakage current, making it suitable for low-leakage current applications.

The V120ZC20PX10 is an excellent choice for applications where overvoltage protection is needed. Its wide operating range, high peak pulse energy, and low leakage current make it a great choice for many applications. It is ideal for use in applications that require a high level of overvoltage protection and reliability, such as industrial automation, power supplies, and communications.
