TVS - Varistors, MOVs products play an important role in providing needed protection from overvoltage and electromechanical transients. The V625LA40A is an ideal solution for this need, offering low-cost protection and consistent performance in a wide range of applications.

The V625LA40A is a multilayer varistor designed to protect against overvoltage transients. The device has two insulated plates, each containing a “positive” and “negative” terminal. When an overvoltage is applied, a voltage-dependent capacitance forms between the two plates. This capacitance then dissipates the overvoltage transient and prevents damage. The varistor itself does not require power and has a fast response to transient phenomena.

The device is most suited for applications that require optimal protection from overvoltage transients, most especially in single phase applications where costly installation and cabling of other protections are not possible or practical. Some key features of the V625LA40A include:

• A low leakage current of 300nA
• A resistance of 28.6kΩ, limiting in-rush current and avoiding an excessive current
• Extreme resistance to mechanical shock and vibration
• A maximum peak current of 400A
• A maximum power dissipation rating of 2.7W

In addition to its electrical protection capabilities, the V625LA40A also offers improved thermal stability characteristics. This makes it ideal for critical applications where temperature variation may be a factor.

The V625LA40A is a popular choice for many electronic applications, including computers, consumer electronics, home appliances, automotive, and communication infrastructure. Some of the most common applications include surge protection for power supplies, overcurrent protection for electric motors, and protection for data lines.

In its most basic form, the V625LA40A is simply two metal plates coated with a silicone-coated epoxy insulation. It has a peak surge rating of 400A and can withstand maximum power dissipation ratings of up to 2.7W. Its small size and low weight make it optimum for use in compact applications where space may be limited.

Overall, the V625LA40A is an effective and reliable solution for providing consistent overvoltage protection in a variety of applications. It is easy to install and designed to withstand a wide range of temperatures and environmental conditions. With its excellent price/performance ratio, it is sure to satisfy the needs of any application that seeks optimal transient protection.
