The V625LU80BP is an 8th Generation Varistor developed by VISHAY, a global leader in passive components. This Varistor is composed of a multilayered metal-oxide-semiconductor array. It is ideally suited for use in transient suppression over an operating voltage range of 6.3V to 333V at 10/1000μs surge current. Its unique combination of silicon oxide and zinc oxide material ensures that it can withstand highly stressed and uncontrolled in-rush current. The V625LU80BP has a high surge rating of 650J and a response time of 25μs. It provides minimal variation in its capacitance values and a low leakage current for improved performance and reliability.

The V625LU80BP is widely used in automotive, aerospace, and consumer electronics applications. It is also suitable for power-assisted systems such as shower control systems, motor control systems, and computer-controlled equipment. Additionally, the V625LU80BP is highly sought after in military applications since it is capable of operating in extreme environments and hazardous locations.

The working principle of the V625LU80BP can be explained by its physical structure. The device consists of 25 layers of silicon oxide sandwiched between two contact electrodes. The outermost layer is coated with a zinc oxide layer for durability and protection. The zinc oxide layer increases capacitance, thereby allowing a voltage-independent response to surges. The layers of silicon oxide increase the breakdown voltage of the device, allowing it to handle higher levels of voltage stress. When a surge of energy is applied across the device, the zinc oxide and silicon oxide layers act in unison to reduce voltage peaks and slow down the discharge of energy.

The V625LU80BP is designed to be robust and reliable in applications where high surge protection is required. The device can also be integrated in electro-mechanical assemblies to provide further protection against high voltage transients. It is easy to mount and has high surge capability, excellent temperature stability, and a long life span. It is also easy to maintain and is compliant with a variety of automotive standards, including the Automotive Electronic Council (AEC) system.

In conclusion, the V625LU80BP is an ideal choice for applications that require high surge protection. Its unique combination of silicon oxide and zinc oxide layers provide high voltage stability and protection from high energy surges. The device has excellent temperature stability and long life span, making it an excellent choice for automotive, aerospace, and industrial applications.
