B72660M0400K072 is an ultra-wide, high-VR type TVS-MOV (Transient Voltage Supressor-Metal Oxide Varistor) with a rated energy dissipation of 4 joules. It has the capacity to absorb large amounts of current in the event of an over-voltage, and protect the connected equipment.

The primary application field for this device is the surge protection of low-voltage systems, from 4.6V to 75V, with its innovative design for ultra-wide application capability. This can include industrial or consumer applications, such as antennas, telephones and modems, power supply applications including DC-DC converters, and automotive applications. The B72660M0400K072 can also be used for over-voltage and over-current protection of 5V, 12V or 24V logic circuits.

The working principle of the B72660M0400K072 is simple. It uses the MOV principle, regulating the voltage at a specified level, and prevents the voltage from increasing higher than this level, no matter how much current is applied. This is achieved by having a metal oxide material that resists changes in applied voltage. When the voltage reaches the varistor’s threshold level, it begins to conduct electricity, and then absorbs energy, dissipating it as heat. The varistor is able to detect sudden changes in voltage and react appropriately to protect the connected equipment, making it robust and reliable.

The B72660M0400K072 also has a wide operating temperature range and a low leakage current, for lower power consumption. It also has a high surge capacity, which is important for protecting circuits that are frequently exposed to high voltage transients or surges. The device also has a low EMI interference level, meaning that it is suitable for use in even the most sensitive applications, such as medical application designs.

In summary, the B72660M0400K072 is an ultra-wide, high-VR type TVS-MOV with a rated energy dissipation of 4 joules. It provides surge protection for low-voltage systems, with its unique design that can protect both over-voltage and over-current situations. It has a wide operating temperature range, a low leakage current, a high surge capacity, and a low EMI interference level, making it suitable for protecting the most sensitive applications. This makes the B72660M0400K072 an ideal device for any application that requires reliable, robust and stable protection.
