B72210S1300K102 is a member of the TVS - Varistors, MOVs family. This surge protection device is designed to protect electronic circuits against electrical overstresses caused by transient events such as electrostatic discharge (ESD), lightning, and other sources. It is produced by the world-renowned German brand EPCOS (TDK).

Application Field

This TVS - Varistor is primarily used on printed circuit boards (PCBs) in medical, aviation, military, automotive, telecommunications, home appliances and other industrial applications. It\'s appropriate for data and power line protection and is ideal for single-phase applications. The device helps to protect circuits in various applications where a conventional MOV may not be enough.

Working Principle

The working principle of B72210S1300K102 lies in its nonlinear resistance character. Under normal conditions, it exhibits a low resistance (<1 ohm), which is frequency-independent. When a voltage transient exceeds its clamping voltage, the resistance of this Varistor increases, thus limiting the peak voltage on the connected line and providing an effective protection. Depending on the application, the available amplitude and the transistor characteristics, the Varistor can clamp the peak voltage to a safe level in nanoseconds.

This Varistor is designed to absorb a large number of impulses up to a pre-set ratio without any visible sign of degradation. It is also immune to polarity reversal, making it a reliable component to use in many applications. The device is temperature-dependent, meaning its electrical characteristics change depending on the operating temperature. This Varistor also offers a high surge current capability and a low inductance feature, making it suitable for high dV/dt applications.

B72210S1300K102 is a reliable surge protection device that can be used for a variety of applications. It helps protect connected electronics and ensures safety in applications with power surges. The device is designed to withstand voltage transients and guarantees lasting protection in a variety of challenging environments.
