TVS - or Transient Voltage Suppressors - devices, such as the B72210S1390K501, are designed to protect sensitive electronic components from damage caused by electrical transients. A transient is a short duration, high voltage electrical overshoot that occurs during normal operation or due to environmental conditions. Transients can create too much heat or voltage that can cause permanent damage to electronic components. TVS devices limit the transient and provide a level of electrical protection for electronic components by diverting the energy away from them.

The B72210S1390K501 is a radial, Leaded Varistor (Metal Oxide Varistor). Varistors act as variable resistors that reduce the voltage of a transient (spike) as it passes through the device. The B72210S1390K501 is constructed of a non-linear semiconductor material, usually some form of zinc oxide, as well as an array of metal electrodes that surround the semiconductor material. When exposed to a transient, the semiconductor material temporarily increases in conductivity, providing low impedance path for the transient and effectively reducing the voltage across it.

The B72210S1390K501 is designed for positive transient voltage surge suppression. It is suitable for most general-purpose applicationsthat require excellent transient surge protection. This Varistor is available with an operating temperature range of -55°C to 125°C, a maximum surge rating of 1500W (8x20µS waveform) and a breakdown voltage of 13.9V. It also features a flame-retardant, UL94V–0 rated UL-approved lead-free RoHS-complianthousing.

The B72210S1390K501 is commonly used in a wide range of applications, including communications systems, consumer electronics, power supplies, automotive, and medical equipment. These devices are also suitable for:

• AV equipment, such as televisions, DVDs, and VCRs
• Computer power supplies
• LED lighting systems
• Industrial machinery
• Others

When designed properly, TVS devices, such as the B72210S1390K501, can provide an effective defense against overvoltage transients, reduce system downtime, and ensure the safe and reliable operation of sensitive electronic components. These devices are relatively easy to design with, integrate, and implement, making them a popular choice when it comes to selecting the right protection device for your application.
