A TVS, or Transient Voltage Suppressor, is an electronic device used to provide protection against electrostatic discharge (ESD), electrical overstress (EOS), and power surges. B72500T140K70 is a particular type of TVS with a breakdown voltage of 140V and a working temperature of -55°C to 150°C. It is typically used in automotive and industrial applications for DC and AC power systems.

A TVS works by limiting transient voltage events such as spikes, glitches, and transients. It diverts power away from sensitive components. Transient voltage suppression (TVS), sometimes referred to as surge protection is used to protect circuit components from voltage transients that can be caused by lightning, electrostatic discharge (ESD), and other electrical events. TVS devices work by clamping voltage levels within a defined range.

The B72500T140K70 is designed to protect against voltage transients that exceed 140V. It is able to provide a protective ESD event holding of 16 kV contact discharges and a surge current of 25 A (8/20µs, 1.2/50µs VBR 175V) while providing low leakage current. It also has a high current handling capability and is designed to handle lightning, ESD, and other transient voltage events with a high degree of immunity.

The B72500T140K70 is composed of a pair of back-to-back Zener diodes. When a voltage surge is experienced, the greater of the two Zener voltages will be forward biased and will allow a current surge through the device. This current is limited by the TVS device\'s internal resistance, limiting the voltage to a safe level. The device will then reset and be ready to protect again.

The B72500T140K70 is suitable for applications in the automotive, industrial, and power electronics industries. It can be used to protect DC and AC power supplies, DC motors, relays, switches, and solenoid actuators as well as other sensitive components from voltage transients caused by ESD, lightning, and other electrical events. It can also be used as an EMI filter for high-frequency noise.

The B72500T140K70 is a reliable and robust device designed to protect sensitive components against a wide range of transient voltage events. With its wide temperature range and high current handling capability, it is well suited for use in automotive, industrial, and power electronics applications.
