TVS diodes, also known as transil diodes, are type of components that are able to protect electronic circuits from voltage pulses which could otherwise damage them. This kind of components are highly reliable and they also have some great features like fast response, low clamping voltage, high surge capability and bidirectional protection. B72580T0131K072 is a high power bidirectional Transient Voltage Suppressor (TVS) diode from the well-known semiconductor manufacturer EPCOS. This particular diode is mainly used in industrial applications like welding machines, motor drives, solid state relays and power supplies.

The B72580T0131K072 is housed in an axial SMD (Surface Mount Device) package with polarity indicator markings in order to easily identify the anode and cathode terminals, making installation a lot easier. Since its body is made of highly thermal conductive material, heat will be efficiently dissipated from this diode. Some of its main electrical characteristics include a breakdown voltage of 550V, a peak current of 200A and a very low reverse leakage current rating of 2.5mA under an applied voltage of 5V. As with other TVS diodes, this component also features excellent clamping voltage and surge current withstand capability.

The operating principle of a TVS diode is as follows. When a transient is applied, the diode momentarily and fastly enters a conducting mode, and in the process the energy that is produced by the surge is absorbed and eventually differences in potential are equalized. As soon as its reverse breakdown voltage is reached, the diode starts to conduct, thus preventing the electrical system from further damage. After the transient is gone, the diode turns back to its non-conducting state, ready to handle a new transient.

The B72580T0131K072 is particularly well equipped for industrial applications, becoming the ideal protection against voltage pulses such as electrostatic discharge (ESD), electrical fast transients (EFT), surge pulses, lightning surge pulses and inductive switching transients. Its well balanced combination of low capacitance, high current and high voltage ratings make this diode a valuable component in almost any electronic system.
