Introduction to the V68ZT10PX2855The V68ZT10PX2855 is a 12.5mm varistor manufactured to protect low voltage DC circuits from destructive overvoltage transients. It’s a low cost solution for circuit protection and transient voltage suppression, and it has a wide range of applications in a variety of industries.What Is TVS or Varistor?TVS stands for Transient Voltage Suppression, and it is a device that is designed to offer protection to electrical systems and components from transient voltage spikes that are above the normal operating voltage of the system. Varistors are one type of TVS devices, and they are used to protect against both positive and negative transient voltage events.Design of the V68ZT10PX2855The V68ZT10PX2855 features a zinc oxide (ZnO) non-linear resistive element that provides transient voltage suppression. This element is highly stable over time and is encapsulated in a ceramic body for ruggedness and reliability. The V68ZT10PX2855 is available with leaded caps and mounting tabs.Applications of the V68ZT10PX2855The V68ZT10PX2855 is most commonly used in low voltage DC circuits that require fast response times in order to protect against the effects of overvoltage transients. These applications include telecommunications systems, computer and consumer electronics equipment, automotive and medical devices, power supplies, and more.Working Principle of the V68ZT10PX2855The V68ZT10PX2855 varistor is designed to suppress fast transients, like ESD, which occur when a high voltage is applied to a PCB or device. The zinc oxide resistive element acts as a short-circuit in order to keep the voltage within the design limits of the system or device. The ceramic body provides high breakdown voltage, noise suppression, and energy dissipation.Features of the V68ZT10PX2855The V68ZT10PX2855 features several important characteristics, which include:

• Fast response time of less than 5µs
• High surge capability of up to 6.5A
• High insulation resistance of greater than 100MΩ
• Low leakage current
• Tin plated terminals for optimal corrosion resistance
• High energy dissipation
• High thermal stability
• Low cost

ConclusionThe V68ZT10PX2855 is an ideal choice for applications requiring protection against overvoltage transients. This varistor offers a high surge capability, fast response time, high insulation resistance, low leakage current, and a wide operating temperature range. With its low cost and reliable performance, the V68ZT10PX2855 is a reliable solution for low voltage DC applications.
