TVS (transient voltage suppressor) devices are devices used in electronic circuits to protect against overvoltage transients. Varistors, MOVs (metal oxide varistors), and active TVS devices are three main types of TVS devices used today. The B72812Q1120S160 is an example of an active TVS device that provides overvoltage protection to components in the system.

The B72812Q1120S160 is a two-stage device with a breakdown voltage of 115V and a low clamping voltage of 16V. This makes it ideal for protecting components with low voltage ratings such as logic circuits, microprocessors, power MOSFETs, LEDs, and other sensitive electronics. The two-stage configuration also allows it to absorb multiple strikes of transient current, making it highly reliable in protecting circuits over its full operating environment. In addition, the B72812Q1120S160 is capable of clamped up to 8A current for short durations, making it capable of heavy transient protection duty.

The working principle of the B72812Q1120S160 is simple – it acts like a sacrificial device that will break down in an overvoltage situation, limiting the voltage and clamping the current. It works by absorbing excess energy of voltage transients by reducing the amplitude of the transient spike. The breakdown voltage acts as the threshold in which the device will break down and absorb the spike, thus protecting the device and the rest of the circuit. When the voltage dissipates, the device will reset itself and can go back to normal operation.

This device’s application field includes protecting components such as microprocessors, power MOSFETs, and other high-speed digital logic components. It can also be used to protect AC power lines, Ethernet or USB lines, and as a switch in power supply networks. These devices can also be used in battery chargers and other power sources to protect against overvoltage and current transients. In addition, this device can also be used to protect against electrostatic discharge (ESD) and lightning.

The B72812Q1120S160 with its two-stage configuration and low clamping voltage is an ideal protection device for many applications in the electronics industry. It has a great ability to absorb transients and at the same time protect components from the damaging effects of overvoltage. Its wide range of applications makes it a popular choice for many electronics engineers and designers.
