TVS (transient voltage suppressors) devices, also known as MOVs (metal oxide varistors) or varistors, are widely used for protection and filtering applications, both on-board and off-board. These devices are typically used to protect electronics from transient voltage events, such as inductive and electrostatic discharges, as well as surge events generated by lightning or other causes. The V480LA80B is an example of a varistor device, capable of withstanding transient voltage events up to 400 Amps (8/20 μs) and maximum peak voltages of up to 480V.

Functionally, this varistor device works by “clamping” rapidly varying transients and by dissipating the energy associated with such events. The device is comprised of two semiconductor layers, each being highly conductive and having its own junction barrier and capacitive coupling. These layers are separated by a zinc oxide layer, which serves to break down at a predetermined voltage across its terminals. When this breakdown occurs, the varistor is “activated” and the energy from the transient is diverted from its source.

The V480LA80B is capable of withstanding large instantaneous peak voltage transients, such as those associated with lightning and other electrostatic or inductive discharges, while maintaining its rated performance and life. Applications for this device include lightning protection, on-board and off-board, as well as protection of equipment from power failure, over-voltage phenomena, as well as other transient events. Additionally, this device can be used as an effective filtering element in AC/DC and DC/DC systems, since it has a fairly low surge impedance and excellent pulse handling capability.

In terms of performance, the V480LA80B is rated to handle transient events up to 400 Amps (8/20 μs), with a maximum breakdown voltage of 480V. Maximum leakage currents are typically no greater than 1 μA, while the capacitance ranges between 130pF to 340pF for the rated voltages. Operating temperature range is -55 to + 85°C, with a maximum storage temperature of 125°C.

In summary, the V480LA80B is an ideal protection and filtering device for use in a variety of applications, ranging from lightning protection to filtering in AC/DC and DC/DC systems. It is capable of withstanding transient events up to 400 Amps (8/20 μs) and has a maximum breakdown voltage of 480V with internal leakage currents of no greater than 1 μA. Its operating and storage temperature ranges are -55 to +85 and 125°C, respectively, making it suitable for use in a variety of environmental conditions.
