Transient Voltage Suppressors (TVSs) are essential components within electronic systems and assemblies, designed to provide protection against voltage transients in a variety of forms. TVSs come in different forms, including Varistors, or Voltage Dependent Resistors (VDRs), and Metal Oxide Varistors (MOVs). The B72587H3300K is an example of an MOV, typically applied to protect heavy-duty equipment from electrical surges. This article provides an overview of the MOV type of TVS device, highlighting the B72587H3300K its application field and working principle.

The B72587H3300K is a surface mount MOV offering effective protection from lightning surges with a high performance current rating of 45A (8/20µs). The MOV is suitable for use with wide voltage ranges, providing effective operation between 11V AC/DC and 510V AC/DC. The device also offers superior protection to both lines with symmetrical peak current rating of both lines.

The main function of an MOV is to provide protection against over-voltages or transient voltages within an electrical system. An MOV functions by rapidly clamping the voltage to a safe level, reducing the amount of stress on the electrical components. When a voltage spike is detected, the MOV quickly diverts the excess energy away from critical components, protecting them from irreversible damage.

The B72587H3300K has a wide range of applications. It is typically used in heavy-duty industrial systems, such as solar energy systems, and as surge protection devices for large power transmission lines. The device is also used in automotive systems, improving the overall protection of the battery and other related components. It is also suitable for many lighting applications, including LED lighting systems.

When applying the B72587H3300K device, it is important to understand its working principle. This component operates through a series of mechanisms, namely capacitance, inductance, and resistance. When a surge voltage is applied to the device, the capacitance immediately stores electrical energy and the inductance briefly holds the energy before the resistance activates. This causes an instantaneous drop in the voltage levels, protecting the components from the damage of a transient voltage.

The B72587H3300K has proven to be an effective transient voltage suppressor, offering reliable surge protection and superior performance. It is also available in small packages ideal for space-restricted applications. This device is used widely across a large variety of applications, including automotive and solar energy systems.
