TVS (Transient Voltage Suppressors) or MOVs (Metal Oxide Varistors) are two forms of voltage suppression devices that provide overcurrent and overvoltage protection by limiting the sustained voltage within a circuit. The V68ZU20PX10 is an example of a TVS or MOV, specifically a Zinc Oxide Varistor.

Varistors, such as the V68ZU20PX10, are non-linear, two-terminal components used to protect sensitive electronic equipment from overvoltages, transients, and overcurrents. The devices have a voltage-dependent resistance (VDR) which, when connected in series with the circuit elements to be protected, performs the voltage clamping function. When the voltage at the terminals of the device exceeds its clamping voltage, current passes through the device, and the device clips or suppresses the voltage.

The V68ZU20PX10 is a medium-power varistor. It provides a symmetrical varistor curve and is designed for the protection of AC as well as DC circuits. Its specific design also allows for reverse polarity applications. The device is capable of dissipating energy up to 10 watts over a wide range of pulse loads, all while maintaining clamping voltages well below the stand-off voltage rating. In addition, the device features a broad temperature range of -40 to +85 degrees Celsius.

The V68ZU20PX10 can be used in a wide variety of applications ranging from consumer electronics to industrial machinery. In consumer electronics, it is often used to protect circuit boards, switches, connectors, and relays from overvoltage damage. In industrial settings, it can be used to protect motor control circuits, automation controllers, and other machinery that are prone to power surges. The device is also suitable for protecting low-voltage and high-voltage digital circuits.

The working principle of the V68ZU20PX10 is based on the voltage-dependent nature of its Zinc Oxide Varistor material. This material has a non-linear, variable resistance that is dependent on the amount of voltage applied. The resistance of the device decreases as the voltage rises, providing protection from voltage transients and overvoltages.

The V68ZU20PX10 is a reliable, cost-effective way to protect electronic components from overvoltage and current surges. Its ability to withstand temperatures of up to 85 degrees Celsius and pulsed loads of up to 10 watts make it an ideal choice for industrial and consumer applications. Its non-linear resistance and symmetrical clamping curves ensure that the device will effectively protect all circuit elements from overvoltage damage.
