Transient Voltage Suppressors (TVSs) are an active form of surge protection that provides higher levels of protection than a simple varistor. They are designed to respond quickly to sudden voltage changes caused by lightning strikes, electrostatic discharge (ESD) and other forms of overvoltage or transient events, suppressing them before they can cause damage to circuitry or components. One common type of TVS is the bi-directional device, which is used for protecting both AC and DC systems. One such device is the B72500E1140S260.

The B72500E1140S260 is a combination bidirectional transient voltage suppressor (TVS), a metal-oxide varistor (MOV), and an electrostatic discharge (ESD) protection component. It features low on-state resistance (RoHS), low capacitance values, wide operating temperature range, and optical transparency. It can withstand transients up to 400A peak surge current rating (Ippmax) and is designed to protect against ESD up to 8kV.

The B72500E1140S260 can be used in a variety of applications, including in computers, servers, laptops, netbooks, tablets, medical devices, telecommunications and consumer electronic equipment. In these applications, the device can provide surge and ESD protection, as well as electrostatic interference mitigation. It is also suitable for automotive applications, including in vehicles such as trucks, buses, and cars.

The working principle of the B72500E1140S260 is based on the same basic principles of standard MOVs and varistors. The device is made up of a metal oxide resistive element, which is connected in parallel with the load. When a surge in voltage, excessive heat, or other transient event occurs, the varistor will absorb the excess energy and dissipate it into the surrounding environment. This will prevent the surge current from being passed through to the load, thus protecting it from damage.

The B72500E1140S260 is designed with a built-in Electrostatic Discharge (ESD) protection circuit. This circuit is designed to protect sensitive equipment from ESD pulses up to 8kV. When an ESD event occurs, the device will absorb the charge rapidly, and then release it slowly over time in a controlled manner. This allows for the equipment to remain protected from any ESD damages.

In addition to surge and ESD protection, the B72500E1140S260 can also be used to provide optical frequency interference (OFI) mitigation. OFI is an electromagnetic pulse which is generated by any abrupt operations of power electronic switches. The device is capable of suppressing these pulses which can interfere with communication signals. This makes the B72500E1140S260 an ideal choice for use in applications where signal integrity needs to be ensured.

In summary, the B72500E1140S260 is a combination bidirectional transient voltage suppressor (TVS), metal-oxide varistor (MOV) and electrostatic discharge (ESD) protection component. It has a wide range of applications, including computers, servers, laptops, netbooks, tablets, medical devices, telecommunications and consumer electronic equipment. It can be used to provide surge and ESD protection, as well as ofi and electrostatic interference mitigation. As such, it is an ideal choice for use in various applications where signal integrity needs to be ensured.
