BPMA150D200LV, also known as Bidirectional Surge Protective Device (SPD) and Thyristor Surge Protector (TSP), is one of the most widely used devices in the TVS - Varistors, MOVs family of varistors. As a multilayer protected, bidirectional, transient voltage suppressor, it\'s mainly used to protect circuits from overvoltage, especially in building wiring, telecommunications, and urban power supply systems and other environments that require surge protection. This article will give an overview of the application and working principles of BPMA150D200LV.

Application field of BPMA150D200LV

BPMA150D200LV, as an important product in the TVS - Varistors, MOVs family of varistors, is widely used in different industries, such as the building wiring, communications, urban power supply systems, and electrical enclosures. It is an ideal solution for various high frequency noise protection in consumer electronics, communication networks, automotive electronics, robotics, and many other electrical and electronic applications.

In addition, BPMA150D200LV is also suitable for EPS power supplies, inverters, CFL lighting, server power supplies, LCD TV power supplies, PCB power supplies, and UPS power supplies. By protecting these products from electric surges, false triggers, transient overvoltage and other damages, it can improve the working efficiency of the products, reduce maintenance cost, and extend the service life.

Working principle of BPMA150D200LV

BPMA150D200LV, as a bidirectional surge protective device (SPD), contains a combination of series thyristors, rectifiers, TVS diodes, resistors, and capacitors. The main function of these components is to suppress a surge in both directions. When an overvoltage signal comes in, such as a lightning surge, the thyristors will begin conducting to absorb the surge energy. At the same time, the rectifier works to reduce the amplitude of the signal and the TVS diodes will clamp the signal to protect the device from damage.

After the surge has been absorbed, the charge stored in the capacitors is released back into the circuit, providing the necessary voltage and current to run the device. This process is usually done very quickly and the surge needs to be persistent for the thyristors to engage. This makes the BPMA150D200LV highly reliable in high frequency noise protection applications.

In order to satisfy different applications, BPMA150D200LV comes with a wide range of configurations for customers to choose from. The customers can choose the most suitable product from these configurations according to their requirements. The configurations range from their rated voltage, let-through voltage, maximum surge current, peak pulse power, leakage current to their internal resistance.

Conclusion

BPMA150D200LV, as an important product in the TVS - Varistors, MOVs family of varistors, is widely used to protect circuits from overvoltages. It contains a combination of series thyristors, rectifiers, TVS diodes, resistors, and capacitors, and it has a wide range of configurations for customers to choose from.
