Transient Voltage Suppressors (TVS) are electrical components, most often made of varistors or metal-oxide varistors (MOVs), that act to protect electronics from voltage spikes of static electricity, lightning or generated internally by the device itself. The B72570D0120A060 is a varistor that provides an interface between the AC line and other components in a circuit to ensure protection against overvoltage transients. It is designed to meet the requirements of UL1449 4th edition for surge protection.

The B72570D0120A060 has a working voltage of 6V with a clamping voltage of 13.1V, and a varistor voltage of 8.2V@1mA. It has a holding current rating of 250mA and a maximum reverse dissipation rating of 0.5W. It has a surge current rating of up to 5KA and a low capacitance rating of 0.3pF. It is UL1449 4th edition compliant, is RoHS compliant, and is self-regenerating after successful implosion or arc-over events.

The typical application field for the B72570D0120A060 is to provide surge protection in a variety of consumer and industrial equipment, including computers, telecommunication equipment, sensitive electronics, power supplies, and electric motors. It can also be used as a voltage regulator, providing stability to a voltage that is subject to large surges or spikes.

The B72570D0120A060 has a working principle that is based on the thermionic emission of electrons. When current flows through a conductor, the electrons are accelerated due to the force of the electric field. When the acceleration is sufficient, the electrons are able to cross the space between the wires, causing an arc or an implosion. The B72570D0120A060 is designed such that the force from the electric field is not sufficient to cause an arc or implosion, therefore ensuring safe operation.

The B72570D0120A060 is designed with a reverse voltage rating of 6V, a clamping voltage of 13.1V, and a varistor voltage of 8.2V@1mA. When a voltage spike occurs, the current passes through the component and is diverted to ground, preventing it from damaging the circuit. When the voltage spike passes, the component is welded back in place and ready to protect against the next surge.

The B72570D0120A060 is a robust metal-oxide varistor capable of withstanding high temperatures and humidity. It is designed to provide reliable surge protection in a variety of applications. With it’s UL1449 4th edition compliance, RoHS compliance, and low capacitance rating, the B72570D0120A060 is a reliable and cost-effective option for surge protection.
