TVS – Mixed Technology, which includes the B1201UARP, is a type of voltage surge protection device that is designed to protect circuits from a variety of transient voltage disturbances. This type of device is commonly used in communications systems, building automation systems, industrial control systems, and other machines or devices that utilize a voltage bus.

The B1201UARP features a hybrid circuit design which combines a voltage-regulated diode (VRD) and a metal-oxide varistor (MOV). The MOV provides protection from internal and external electrostatic discharge (ESD) and other fast-changing voltages, while the VRD blocks dangerous over-voltage and inrush currents. The combination of the two technologies in the B1201UARP provides increased protection from both common mode and differential mode transients.

The B1201UARP’s working principle is to detect and divert voltage surges in order to protect sensitive electronic components. An over-voltage spike can cause catastrophic failure to a circuit or component, so a surge protector works to protect the components from these transients. When a voltage surge occurs, the detector initially senses it and then the surge diverter dissipates the energy. The MOV element of the B1201UARP acts like a resistor and clamps the voltage to a safe level. The VRD helps to regulate the incoming voltage so that it does not exceed the rated value.

The B1201UARP is designed to provide protection in four major fields. First, it can protect against electrostatic discharge (ESD) and over-voltage transients. Secondly, it prevents arcing and arc-blast damage that can occur in wiring systems and between contacts. Thirdly, it suppresses transient voltages due to inductive switching, which can be caused by switching of motors, relay contact closure, and other sources. Lastly, it suppresses the voltage spike caused by the surge current of fuses and circuit breakers.

The B1201UARP is designed to meet or exceed industry standards for surge protection devices. It is RoHS compliant, UL recognised, and UL certified for both VDE and CSA certification. It also has a low leakage current and withstands a wide temperature range (between -40°C and +105°C). Additionally, it has a high surge current rating (6000A, 8/20 μs) and a wide operating voltage range (80-630 VAC).

In conclusion, the B1201UARP is a mixed technology surge protection device that is designed to protect sensitive circuits and components from voltage transients and surges. It combines both VRD and MOV technologies in order to provide increased protection from over-voltages, ESD, inductive switching transients, and surges from circuit breakers and fuses. The device is designed to withstand a wide temperature range and has a high surge current rating. It is also RoHS, UL, VDE, and CSA certified, making it a reliable and effective surge protection solution.
