TVSs (Transient Voltage Suppressors) are electrical devices used to protect electronics from voltages beyond its threshold score. Varistors, MOVs (Metal Oxide Varistors) are an essential part of TVSs. TVSs suppress over voltages in input sources, protecting internal and sensitive components from damage caused by short term power surges.

B72587G3140S253 is a type of TVS varistor that is used for protection from lightning, power transients and electrostatic discharge. It’s a digital varistor developed for reliable protection of automotive electronics from power transients. These components provide an ideal ESD solution for any automotive system.

Application field: B72587G3140S253 is widely used in the automotive industry in order to protect power lines, ignition coils, and main electronic components. In this field, these components provide efficient protection for components of varying voltage situations. Specifically, the B72587G3140S253 can be connected to power supplies up to 14V to provide electrostatic discharge protection. Additionally, it can protect against high voltage reverse clamping for IC protection when subjected to transients.

Working Principle: B72587G3140S253 works through a combination of electrical characteristics, such as its capacitance and resistance. At low voltages, this component is a low-resistance capacitor. When the voltage increases to a certain threshold voltage (Vr), its resistance changes rapidly and its capacitance drops, enabling a fast discharge in order to prevent the power surge. They are also a good choice for EMI suppression.

When subjected to a transient overload or induced surge, the B72587G3140S253 acts as an open circuit, limiting the current by shunting it to ground. The component then dissipates the energy through heat in the resistor, allowing the system to remain stable and protected. These components come with two current ratings, 130A or 150A, and require no additional circuit design.

S275G3140S253 varistors are suitable for use in a variety of automotive, railway, marine, and industrial equipment. These components can be easily implemented in a multitude of designs without any additional design considerations. Because of their simple implementation requirements, these components are cost-efficient and you can expect to get a good return on investment with this type of TVS.
