The TVS Device type B72510E2170K062 is a Multi-Functions Over Voltage / Over Current protection Device. It has an over voltage protection (OVP) threshold of 14V, and an over current protection (OCP) threshold of 1.7A. It can be used in various applications, such as over voltage and over current protection in automotive and industrial application.

Application Field

As a Multi-Functions Over Voltage / Over Current protection Device, the B72510E2170K062 has numerous applications in Electrical & Electronic systems, especially in Automotive and Industrial applications. It is mainly used in Automotive and Industrial sectors for voltage and current surge protection, protecting connected circuits from any kind of electrical overvoltage and over current.

In automotive sector, it is used for controlling and stabilizing voltage spikes and current surges, like when excessive current flows through the system owing to overloads, short circuits and electrical noises. In industrial control systems, installations and other similar applications, this TVS device helps in protecting sensors, transistors and other components from any kind of EMI (Electromagnetic Interference).

The B72510E2170K062 also finds applications in any kind of system, where voltage or current surges need to be monitored and protected against. These type of applications are usually found in consumer electronics, telecommunications, medical equipments, power charging and other similar applications.

Working Principle

The B72510E2170K062 works by clamping the voltage reaching beyond the specified thresholds. If the applied voltage exceeds its over voltage protection (OVP) threshold, voltage is clamped. Likewise, when the current exceeds its over current protection (OCP) threshold, the device limits current to prevent the connected circuit from damage.

The device consists of two components, a thermally spaced varistor and a limiting element. The varistor is capable of absorb high electrostatic discharge, while the limiting element limits the current by using either the principle of resistor or semiconductor element. In cases of over-voltage and over-current, the limiting element will activate and clamp the voltage and current, thereby protect the entire system.

The B72510E2170K062 also features an integrated temperature monitor in order to prevent from thermal-stress or over-heating. If the temperature exceeds a certain threshold, the device will shut down thus preventing from any further damage.
