V47ZT7P Circuit Protection

A Varistor, also known as a voltage-dependent resistor (VDR), is an electronic component with a variable resistance that is dependent on the voltage applied across it. Varistors are mainly used to protect circuits from high voltage surges.

A Metal-Oxide Varistor (MOV) is a variation of the traditional varistor, fabricated from a metal oxide such as zinc oxide or tin oxide. It is usually formed from a combination of two materials, a ceramic disk and a metal alloy, and is known for its ability to dissipate large amounts of energy.

The V47ZT7P is a MOV with a 7mm disc and a leaded terminal. It is designed to protect against high direct current and surge voltages. Its rated impulse voltage is 47V and its peak surge current is 10kA.

The V47ZT7P works by diverting electricity from the protected circuit to the ground. When a surge voltage is applied to the protected circuit, the metal-oxide component of the V47ZT7P varistor absorbs large amounts of energy, which is then dissipated into the ground. By absorbing the energy, the MOV prevents the protected circuit from experiencing a voltage overload.

Due to its ability to absorb large amounts of energy, the V47ZT7P is used for a variety of applications, including:

• AC and DC power line suppressors
• Lightning protection for fixed installations
• DC motor switch protection
• Communication line protection
• Surge protection for sensitive equipment

The V47ZT7P can also be used in a variety of industrial, commercial, and residential applications. It is commonly used in surge protection devices, as well as in surge suppressors, power boards, and industrial control systems. The V47ZT7P can also be used in spas, swimming pools, and other water-bearing equipment.

The V47ZT7P is a reliable and cost-effective solution for protecting circuits from overvoltage and transients. Its ability to dissipate large amounts of energy while keeping the protected circuit safe make it a popular choice for a variety of applications.
