Transient Voltage Suppressors (TVS) are commonly used to protect sensitive electronic components from the risks of overvoltage. These devices have an important role in the design of both AC and DC circuits, as they are designed to offer protection from voltage spikes that can cause serious problems. One example of a TVS is the 0071.3281.B1 varistor, which is a device used to suppress transients by safely dissipating their energy.

The 0071.3281.B1 is a Metal-Oxide Varistor (MOV), a type of TVS which uses the non-linear breakdown characteristics of metal-oxide materials to protect circuits. As voltage levels rise above the specified limit, the device limits the amount of current that is allowed to pass through the circuit, thus protecting the components from damage caused by electrical transients.

The working principle of the 0071.3281.B1 is quite simple: A zener-type diode is connected to a metal-oxide refractory, which is typically a zinc oxide or a cadmium sulfide. When a transient voltage spike occurs, the current flow increases, activating the diode. This causes a voltage drop across the diode, initiating current conduction in the MOV. The MOV then absorbs the excess voltage, protecting the circuit from damage.

The 0071.3281.B1 is suitable for use in a variety of applications, including AC power line surges, DC motor control circuits, lightning protection, and automotive and automotive accessory circuits. It can be used in any circuit where high-frequency transients or large surges need to be suppressed.

The 0071.3281.B1 is designed for use in both AC and DC circuits and offers a wide surge current capability. It is capable of dissipating up to 72 amperes of repetitive peak surge current and 10 amperes of non-repetitive peak surge current. The operating voltage range of the device ranges from 6 to 250 volts and it has a leakage current of less than 75 microamperes at 1 second.

The 0071.3281.B1 is a highly versatile device and is suitable for a wide range of applications, including power line surge protection, safety cover circuits, DC motor control circuits, automotive circuits, and lightning protection. The device offers reliable protection against dangerous surges and is capable of withstanding high overload conditions.
