TVS - Varistors, MOVs

The B72214S1390K501 TVS is a popular component with a variety of applications in electronics and electrical systems. It is a Transient Voltage Suppressor (TVS) which is also known as a Varistor or a Mov (Metal-Oxide Voltage Limiter). In this article we will look at the B72214S1390K501 application field and its working principle.TVS devices, such as the B72214S1390K501, are used in electronics to protect against overvoltage transients. A transient is an unwanted and sudden change in voltage, usually due to lightning, electrostatic discharge, switching transients, or other environmental factors, that could potentially damage a Circuit. These devices absorb the energy of the transient and dissipate it to limit the voltage to a safe level.The B72214S1390K501 is a unidirectional, or unilateral, TVS diode. It has a breakdown voltage of 14 volts (VBR) and a working voltage of 13.9V. It has a maximum leakage current of 1.2 μA and a clamping voltage of 27.9V at a working current of 400mA. Its peak pulse current (IPP) is 1.4KA (10/1000s) and its clamping voltage is 37.8V at a working current of 1KA (10/1000s). The B72214S1390K501 is designed to be used as a protection device in DC/DC converters, relay coils, power circuits, Ethernet and USB ports, and in automotive electronics. It is also suitable for use in plane, mobile, and stationary audio systems, TVs, and home appliances. Now that we have covered the B72214S1390K501 application field, let\'s take a look at how it works. The B72214S1390K501 is a semiconductor device made up of two layers of metal-oxide. The inner oxide layer acts as a dielectric while the outer layer acts as a conductive layer. When the input voltage on the TVS exceeds its breakdown voltage (14V), current flows through the device in a reverse direction. This current causes the outer layer to become polarized, which means that the electrons in the metal-oxide are rearranged to absorb the electrical energy from the transient. The polarized layer then acts as a diode, blocking the flow of current and preventing the voltage on the circuit from exceeding its breakdown voltage. The B72214S1390K501 also has overvoltage protection and overcurrent protection which ensures that the device won\'t be damaged by long-term overvoltage or overcurrent.In summary, the B72214S1390K501 is a very useful device with many applications in electronics and electrical systems. Its overvoltage protection and overcurrent protection make it a safe and reliable choice for a wide range of applications. Its working principle is based on a semiconductor structure which absorbs and dissipates energy from transients, preventing them from damaging the circuit.
