TVS - Varistors, MOVs, are electronic components that perform transient voltage suppression for transient voltage events in power systems. One of the most common applications for a TVS is in communications networks, where overvoltage surges could damage sensitive equipment. The purpose of a MOV is to absorb transient voltages that would otherwise damage or otherwise affect the performance of other components in the system. The B72540T6500K062 is one such device from Infineon Technologies AG.

The B72540T6500K062 is a highly robust, transient voltage surge suppressor (TVS) diode designed for ESD and lightning protection. It features a dual topology and bidirectional symmetric protection for mobile phones, automobile consoles, I/O ports, and other sensitive electronics. The device is constructed with a SiO₂ and poly-oxide field-effect transistor (FET) network, and is designed to offer a high level of protection from electrostatic discharge (ESD), electro-magnetic interference (EMI), and lightning.

The device has a low on-state voltage drop of less than 2V, which is suitable for automotive applications where the device must operate at low voltage. It is also built with a low-impedance design, allowing it to absorb high ESD strikes of up to 25kV. The B72540T6500K062 can also provide protection for up to six circuits simultaneously, making it an ideal choice for protect multiple circuits from transient surge events.

The working principle of the B72540T6500K062 is based on the avalanche breakdown of a reverse-biased p-n junction. In this case, an avalanche breakdown will occur when the reverse voltage applied to the device is greater than its rated breakdown voltage. The avalanche breakdown generates large numbers of hot carriers that dissipate the energy of the incoming transient voltage across the device, thus protecting the system’s circuits from the surges.

The device is also designed to react very quickly to transient voltage surges, providing a high level of protection from overvoltage events with little delay. The device’s response time is faster than the time required for a shunt resistor to react to the transient voltage, thus offering increased protection against voltage transients.

The B72540T6500K062 is an ideal choice for many different types of applications, including automotive systems, industrial systems, and telecommunications systems. It is a highly robust device designed to provide reliable protection from a variety of transient voltage surges. The device is well-suited for applications in which there is a need for protection from both ESD and lightning events. Its response time, low-impedance design, and low-on-state voltage drop make it an ideal choice for a variety of different applications.
