BSPM4240HLG

TVS (transient voltage suppressors) and MOVs (metal oxide varistors) are two important components in modern electronic systems. They are used to protect the system from potentially damaging transients caused by external electromagnetic disturbances, such as lightning strikes, power surges and overvoltage conditions. BSPM4240HLG is a device that combines both the features of TVS and MOVs. It is designed for applications with high reliability and fast response times.

The BSPM4240HLG is an ultra-fast, high-current device that is designed to protect the system from transients and overvoltage conditions in a variety of applications, such as industrial, networking, telecom, and consumer electronics. It has a wide operating temperature range of -55°C to +125°C, and is capable of handling surge currents up to 25A without damage. The device features an ultra-low leakage current and low capacitance, which allows for fast response to transient events. It also provides inherent ESD (electrostatic discharge) protection capabilities.

The working principle of the BSPM4240HLG is based on a varistor approach, where the device consists of an array of metal oxide varistors, or MOVs. The MOVs are used to provide suppression of high-voltage transients and attenuate electrostatic discharge currents. When subjected to an overvoltage pulse, the MOVs provide an internal short circuit across the terminals, thus clamping the voltage at the terminals and preventing further voltage transients from entering the system. This ensures fast circuit protection from damaging voltage transients.

The BSPM4240HLG also features built-in thermal protection that prevents permanent damage in case of overloads. In addition, its construction allows for excellent line-to-line protection against common mode transients. All these features make it an ideal device for a wide range of protection applications.
