Introduction

B72210S0140K101 is a type of TVS-MOV (Transient Voltage Suppressor-Metal Oxide Varistor) develped by Siemens. It is designed to provide surge protection to a wide range of microelectronic components and systems. The device is a bidirectional over-voltage protection device that works by dissipating high over-voltage surges. It can also be used as a very low impedance protective device in certain applications.

Application Field

B72210S0140K101 is ideal for use in hostile environments. It is perfect for applications that require very high reliability and surge protection. It is suitable for environments that experience long term energy exposure, such as those found in industrial, automotive, and military applications. It is also often used to protect sensitive telecom equipment, medical systems, control systems, and other sensitive electronic components.

Working Principle

The working principle of B72210S0140K101 is based on voltage degradation. When an over-voltage surge is detected, the protective device will start to degrade the voltage of the surge to a level below the operational threshold of the connected components. This process occurs instantaneously as soon as the surge is detected, providing excellent protection.The device also features a low capacitance/impedance rating which allows for fast discharge of the over-voltage surge. This provides a very effective protection against any transient surges, eliminating risk of damage to connected components.

Conclusion

B72210S0140K101 is a reliable and robust over-voltage protective device. It is designed to provide protection in hostile environments, making it perfect for sensitive telecom and medical applications. It works by degrading the voltage of over-voltage surges to levels below the operational threshold of any connected device, while also featuring a low capacitance/impedance rating for fast discharge. This ensures excellent protection against any transient surges, making it a reliable and valuable choice for any application.
