Gas discharge tubes, also known as spark gaps, can be useful components in a vast array of applications. Of all the gas disclosure tubes available, the B72520V0200K072 is becoming increasingly popular due to its versatility and ability to protect from exposure to overvoltages.Classified as part of the TVS (Transient Voltage Suppressors) – Varistors, MOVs (Metal-Oxide Varistors) family of products, the B72520V0200K072 is used in circuits to shunt damaging high voltage surges. This is done by providing a low impedance path to ground when a predetermined amount of voltage is exceeded. As such, it is ideal for protecting sensitive components from damage due to lightning, power transient transients, ESD (electrostatic discharge) and other overvoltages.The structure of the B72520V0200K072 is a layered structure similar to other gas discharge tubes. The device has two electrodes, one insulated by a protective material to create a precise gap between them. Inside the gap, a low pressure gas (argon or nitrogen) is present which is capable of conducting electricity. This gas coupled with a resistor in the base layer of the gap creates the triggering mechanism that allows the device to detect surges or ESD events.When an overvoltage occurs, the voltage in the gap is increased which causes an ionization of the gas allowing electrons to flow and complete the circuit. The current which is created when this happens is shunt to ground and creates a low-impedance path which dissipates the energy. This creates a \'clamp\' effect, and prevents the overvoltage from continuing onto the circuit which would cause further damage.The B72520V0200K072 is capable of suppressing transients from -6 to +1000V (@20A) and has a maximum surge current of 6000A. Additionally, it has a maximum resistance of 0.1 ohms which offers excellent protection capabilities.Due to their performance characteristics, the B72520V0200K072 is used in a range of applications including telecommunications equipment, power supplies, high voltage motor drives and electronic motor controls.In conclusion, the B72520V0200K072 is a versatile and highly capable gas discharge tube designed to shunt damaging high voltage surges to ground. It has an excellent capability of suppressing transients from -6 to +1000V and is used in a variety of different applications. As such, it is becoming a popular choice for those looking to protect their circuits from exposure to overvoltages.
