TVS – Varistors, MOVs is an abbreviation that stands for Transient Voltage Suppressors, or simply circuits that are designed to protect a circuit from damage caused by transient voltage spikes. B72250L0421K102 is a type of TVS device used to suppress overvoltage transients, or spikes, on circuits and components.

The B72250L0421K102 consists of two components: two series-connected, non-linear, metal-oxide varistors, or MOVs, connected in a symmetric bridge configuration and an integrated thermal protection device. The MOVs act like a voltage-controlled resistor, so that when the voltage across them exceeds a certain peak level, they become conductive, limiting the voltage. The integrated thermal protection device is a positive temperature coefficient (PTC) resistor that is housed in the MOVs, which provides a fuse-like action and shuts down the MOVs in the event of an overload.

The B72250L0421K102 can handle up to 3 kV of transient voltages and up to 8 A of current. It is suitable for a wide range of applications in power supplies, industrial electronics, automotive electronics, and audio and video equipment. For example, it can be used to protect computers, phones, and other delicate electronic devices from spikes in the voltage from lightning or electrical power surges.

The B72250L0421K102 is also designed to protect against ESD, or electrostatic discharge, which is caused when the voltage between two objects is significantly different from the ambient electrical environment. The device is designed to suppress ESD strikes as low as 8 kV contact discharge and 15 kV air discharge, so it can be used in applications such as consumer electronics, medical equipment and industrial machines.

In addition to being used to protect circuits against overvoltage protection, the B72250L0421K102 can also be used for short-circuit protection. When a short-circuit occurs, the device will shut down the circuit and protect it against damage from excessive currents. It can also be used to provide a degree of overload protection to protect the circuit from overload conditions that may arise from components or wires that are improperly matched.

Overall, the B72250L0421K102 is an effective way to protect circuits and components from transient voltages and surges, as well as providing protection against ESD and short-circuit conditions. It is suitable for a wide range of applications, including consumer electronics, automotive electronics, power supplies, industrial electronics, and audio and video equipment, making it a versatile and reliable solution for protecting circuits and components.
