TVS (transient-voltage-suppressor) varistors, MOVs (metal-oxide varistors) and other varistor-type devices are electrical components used for protection from transient voltage events. These off-the-shelf devices provide a wide range of characteristics and selectivity for an application. The ability to turn off within a few microseconds makes them attractive in areas such as over-voltage protection, lightning protection, surge protectorcoupling and clamping.

The 0070.5061.A2 transient-voltage-suppressor varistor is a two-terminal, surge-protective device used to protect electronics in extreme voltage events. It provides a conducting path by diverting electrical energy between two points, providing overvoltage protection in delicate, sensitive or mission-critical electrical and electronic equipment. The 0070.5061.A2 is designed to withstand transient events in a wide variety of applications, including telecommunications, medical equipment, automotive, and industrial power electronics.

The 0070.5061.A2 varistor has a rated peak voltage (Vp) of 700V, a peak current (Ip) of 1kA, and a capacitance of 0.8pF. The varistor has an advanced polymer construction for trade-off performance and reliability. It is capable of a non-linear, bidirectional, symmetrical current-limiting response, providing a solution for overvoltage and transient protection.

The 0070.5061.A2 varistor is ideal for applications that require instantaneous protection from high-frequency electrical transients, such as lightning and high-voltage spikes. The advanced design minimizes power losses and minimizes the time to recover from a transient event. It is capable of handling high peak surge currents and protecting delicate electronic components. The low leakage current helps to reduce the amount of heat generated.

The working principle of the 0070.5061.A2 varistor is based on an intrinsic property of nonlinear materials such as zinc oxide, which allows them to operate with a nonlinear current-voltage (I-V) relation. Under normal operating conditions, the varistor behaves like an insulator, blocking any current from passing through it. When the applied voltage exceeds the rated voltage of the varistor, the device will become forward-biased, allowing an abrupt increase in the current flow, allowing the current to be “clamped”. The instant on nature of the 0070.5061.A2 varistor makes it highly suitable for high-voltage protection applications.

The 0070.5061.A2 varistor is ideal for applications where fast and reliable surge protection is required, such as automotive, medical, computer and telecommunications equipment. The surge protective device provides protection from electrostatic discharges (ESD) and lightning. It is capable of operating in the temperature range of -55°C to +85°C, making it suitable for use in most environments. It also has a low self-capacitance that minimizes inductive ringing and un-clamping time.

The 0070.5061.A2 varistor is a valuable asset for any application requiring fast, reliable and safe overvoltage protection. This device provides the necessary functionality and features to ensure maximum safety when power surges occur. It allows manufacturers to easily integrate overvoltage protection into the design of their products, offering their customers reliable protection and peace of mind.
