<HTML><BODY><p>TVS - Varistors, MOVs stands for Transient Voltage Suppression – Varistors and Metal Oxide Varistors, and these are two different types of Voltage Suppressors. The B72590D0120H060 is an example of a MOV (Metal Oxide Varistor). It is most commonly used for Surge Protection in high voltage installations, as it has the ability to not only suppress the current transients, but also to absorb and dissipate the high energy pulses.</p><p>The B72590D0120H060 has a very wide range of application fields, ranging from lightning protection in high voltage installations, to over-voltage and over-current protection for electronic systems. In addition, it can be used as an ESD suppressor in static sensitive components, and also for filtering and protecting electro-mechanical switches and contacts. This type of Voltage Suppressor is also suitable for applications where a highly accurate, nonlinear voltage response is required, such as in power supplies and signal conditioning systems.</p><p>The B72590D0120H060 consists of an integrated circuit of two metal oxides, which are bonded to a substrate material. The substrate material is porcelain and this is where the electrical contacts are placed. The two metal oxides make up two different layers in the circuit. The first layer is a dielectric layer, which consists of a Zener diode and a transistor. The second layer is a resistive layer, which consists of a silicon dioxide resistor and a special PTC resistor. These layers are designed to provide maximum protection against transients, over-voltage, and over-current.</p><p>The working principle of B72590D0120H060 is quite simple. It works by applying a large current to the dielectric layer. This current causes the dielectric layer to heat up, which then dissipates the excess energy, preventing damage to the protected components. When the current flow reaches a threshold level, the resistive layer causes the current to be diverted away from the protected components, which prevents further damage. The current is then dissipated into the substrate material.</p><p>As well as its wide range of applications, the B72590D0120H060 is also a very reliable Voltage Suppressor device. The device is able to withstand large variations in temperature without any detriment to its performance, and is also capable of absorbing very large voltage transients with no loss of power or signal integrity. This makes it an ideal choice for protecting components in extreme temperatures or environments.</p><p>In summary, the B72590D0120H060 is a versatile and reliable device which is suitable for a wide range of applications. Its ability to suppress voltage transients and its temperature tolerance makes it an ideal choice for protecting components in both low and high voltage installations.</p></BODY></HTML>The specific data is subject to PDF, and the above content is for reference
