The 0070.7521.A2 is classified as a TVS - Varistors, MOVs. It has various applications in different industrial settings, such as automotive, military and medical, and it can help prevent electrical failure due to surges and spikes. Thus, it is an important device in industrial operations.

This device is basically an overvoltage protector. It is designed to automatically switch off the circuit if the voltage exceeds a set threshold. It is primarily used to protect circuits from high voltage spikes and transients. This includes everything from voltage surges due to lightning strikes to the overvoltage that can be caused by equipment switching operation. By maintaining proper voltage levels in the circuit, this type of device helps prevent the occurrence of dangerous electrical fires.

The 0070.7521.A2 works by using a combination of metal oxide and ceramic material as the nonlinear element. This nonlinear element is designed to provide a specific voltage level where it can tolerate a certain amount of energy per unit charge. It will only fire if the voltage is higher than this preset value. It also needs to have a dielectric strength high enough to keep its circuit board connection from melting or being damaged due to high voltage.

This type of device also allows for a broad range of clamping voltages that can be applied to the circuit board for various operations. This range depends on the type of metal oxides and ceramic material used. The combination of these materials provides the necessary energy absorption to safeguard the devices.

When the voltage levels exceed the preset value, the 0070.7521.A2 will activate and switch off the circuit. The device is designed to stay in the off position until the voltage levels return to normal. This prevents the risk of any further overvoltage situations that can lead to damage or destruction of the equipment.

Given its importance in various circuits and its different applications, parameters such as surge current and holdover voltage levels become significant. While designing a particular circuit, these parameters must be carefully studied and verified for the device to work correctly. Other factors such as EMI (electromagnetic interference) or RFI (radio-frequency interference) should also be taken into consideration.

In conclusion, the 0070.7521.A2 is an important device for a variety of industrial applications. Its ability to switch off the circuit under overvoltage ensures a safe environment. Its wide range of clamping voltages and other parameters make it an ideal choice for many industrial operations. It is an important part of an overall electrical circuit protection system.
