TVS - Varistors, MOVs, and B72225S4381K101 are all components that control and limit transient high voltage. Voltage surge protection is extremely important in many industries to protect electronics from being damaged by voltage spikes. B72225S4381K101 is a compact, bi-directional suppressor that is used in various electronic products. It’s designed to provide a broader protection range than traditional varistors or MOVs. Let’s take a closer look at this suppressor and its application field and working principle.

The B72225S4381K101 solid-state suppressor was designed for use in applications where surge events up to 12A/5V, including lightning or ESD, might occur. It is a general-purpose device that is widely used in consumer electronics such as digital cameras, audio amplifiers, DVD players, circuit boards, medical equipment, and satellite receivers.

The main components of the B72225S4381K101 are metal-oxide varistors (MOVs), which provide protection against transients. These MOVs limit transient voltages by providing a low-resistance path to ground when the surge voltage reaches the avalanche voltage of the MOV. The MOVs absorb the energy of the surge and clamp the voltage to an acceptable level. Since this suppressor uses a combination of MOVs and a transient voltage suppression (TVS) component, it provides significant protection against electrical surges, while the ability to absorb a large amount of energy makes it suitable for use in EMI/RFI sensitive equipment.

The working principle of the B72225S4381K101 is relatively simple. It works by redirecting the surge current to ground. When a high voltage occurs, the MOVs will be triggered, allowing the current to travel through the relay contacts to ground. Once the MOVs absorb the energy of the surge, the contacts will open, allowing the circuit to return to normal. The TVS component of the suppressor also works by clamping the voltage to an acceptable level, which prevents the electrical surge from damaging the electronics.

In conclusion, the B72225S4381K101 is a popular type of surge protection device. It is suitable for a wide variety of applications, including consumer electronics, circuit boards, and medical equipment. Its efficient operation and combination of metal-oxide varistors and a transient voltage suppression component make it an ideal choice for surge protection.
