TVS - Varistors, MOVs, devices are common surge and over voltage protectors used in electrical and electronic circuits. The B72542V3140S572 is a type of varistor used for over-voltage protection.

The B72542V3140S572 is a bidirectional varistor that is used to absorb overvoltages that arise due to transient overvoltage conditions in AC and DC line to ground acts as a shunt to allow the capacitor within the power supply filter to smoothly clamp the overvoltage within the required range without causing a high voltage transient on the DC line. The device is available in a varistor series with VDR values up to 2800V and maximum peak current ratings up to 40A.

The B72542V3140S572 is a low-profile, high-capacity shut-off device that absorbs surges and overvoltage transients. Its bidirectional nature makes it ideal for protecting both AC and DC power circuits from undesirable overvoltage events. To provide maximum protection, the device has a low-resistance source for dissipating energy at high current levels. The device also has a high-current capability that can dissipate up to 15 kilojoules of energy in a single event.

The device is designed to protect electronic circuitry against lightning, electro-static discharge, fluctuating AC voltages, inductive loads, and power-induced transients. In the event of an overvoltage, the device will absorb the energy and initiate a rapid shut-off, thereby protecting the power circuit. The device also includes a shut-off signal output that indicates the status of the varistor and can be used to disconnect the power supply in the event of an overvoltage.

The B72542V3140S572 is appropriate for use in a variety of power conditions, such as in switching power supplies, which experience a wide range of voltage fluctuations. Its very low VDR clamping value helps to prevent the propagation of high voltage transients into sensitive electronic circuitry. The device is also suitable for implementation in power supply filter designs due to its low DC resistance and high-current capability.

The working principle of the B72542V3140S572 can be summarized as follows: The device employs a single varistor to absorb transient overvoltage events and discharge the stored energy through the internal shunt resistor. The device is designed to absorb energy at a rate that is lower than the rate of energy dissipation. This allows the device to operate at low Temperature-Rise-Voltage (TRV) levels and provides a high level of reliability and safety.

The B72542V3140S572 is an ideal solution for both AC and DC overvoltage protection applications. Its low VDR clamping value helps to ensure safety and reliability, while its high current capability allows for maximum energy absorption in the event of an overvoltage. The device provides superior overvoltage protection and is suitable for a variety of power circuit conditions, making it a great choice for any application that requires reliable overvoltage protection.
