TVS-Varistors, MOVs are components used to protect semiconductor devices and circuit components from transient voltage or electrical overstress (EOS). They are widely used in power supplies, lighting circuits, automotives, consumer electronics and communication devices. The BSPM2480S3GR is an example of such a TVS component, which is designed to absorb transient voltages in the range of 8 to 24V and has a transient current surge rating of 24A.

The BSPM2480S3GR is effectively a multilayer ceramic capacitor, consisting of a stack of multiple layers of ceramic and metal. It comprises of an external metal casing, an internal ceramic element, a ceramic-metal outer layer, and multiple ceramic-metal inner layers. The internal structure is designed to induce a highly capacitive charge when exposed to transient voltages, effectively absorbing and dissipating the transient energy as heat. The internal ceramic dielectric element is made of material with low residual skin effect, and it is able to maintain very low resistance in different frequencies.

The BSPM2480S3GR is mainly used in power supplies, lighting circuits, consumer electronics, and communication devices. In power supplies, it can be used to protect sensitive components such as processors from high voltage transients caused by lightning strikes or switching events. In lighting applications, it can be used to protect against voltage spikes caused by incandescent bulb or LED switch off. In consumer electronics, it can be used to protect against transient voltages such as electrostatic discharge (ESD). In communication applications, such as base stations, it can be used to protect against high voltage transients caused by lightning strikes or other sources.

The working principle of the BSPM2480S3GR is based on two components: capacitance and dissipation. When exposed to a transient voltage, the capacitor absorbs energy and the internal ceramic dielectric element, induces a capacitive charge which is stored within the ceramic layers. The stored energy is dissipated as heat through the internal resistors, thus protecting the device from EOS damage. The residual resistance is determined by the material and thickness of the ceramic-metal layers and varies depending on the transient voltage. The transient energy surge rating is determined by the maximum voltage and current rating of the device.

The BSPM2480S3GR is an example of a TVS component, which is used to protect semiconductor devices and circuit components from transient voltage and electrical overstress. It has a wide range of applications in power supplies, lighting circuits, consumer electronics, and communication devices. By using a combination of capacitance and dissipation, it can effectively absorb transient voltages and dissipate energy as heat, thus protecting against EOS damage.
