Varistors, commonly known as voltage dependent resistors or VDRs, are solid state, nonlinear components that protect circuits against voltage transients. They are often used to prevent damage due to voltage spikes, transients, and overvoltage situations. The V39ZA20PX2855 is a varistor manufactured by Visaton for your application needs. This state-of-the-art device features a low response time and excellent surge protection.

The main function of a varistor is to absorb excessive transient voltages from electrical power and component signals. This is achieved by clamping the voltage spikes to an acceptable level. If the voltage spike is higher than this level, the varistor will act like a resistor, allowing the excess voltage to dissipate. This protects the circuit from damage due to overvoltage and reduces the possibility of a breakdown. The V39ZA20PX2855 can be used for a range of applications that require surge protection.

The V39ZA20PX2855 is a metal-oxide varistor. It has a very low leakage current and features a capacitance of 4pF. It is designed for a maximum operating voltage of 250V, a rated power of 250mW, and a maximum varistor voltage of 320V. The device is also RoHS compliant and has an operating temperature range from -55°C to 175°C.

The working principle of a varistor is based on the property of its semiconductor material, zinc oxide. When a voltage spike is present, the zinc oxide will act like a diode, conducting current in only one direction. The current flow will be in the direction away from the voltage spike and the excess energy is dissipated. This limits the voltage transient to a safe level for the circuit.

The V39ZA20PX2855 is a very versatile device and can be used for a wide range of applications. It is suitable for use in telecommunications, audio systems, medical equipment, industrial electronics, computers, and automotive electronics. The device can be used to protect electronics from voltage surges, voltage transients, and overvoltage conditions. It also helps prevent electrostatic discharge damage.

The V39ZA20PX2855 is a high quality varistor from Visaton. It is designed to provide surge and transient protection for a range of applications. The device features a low leakage current, low response time, and excellent surge protection. It is suitable for use in telecommunications, audio systems, medical equipment, industrial electronics, computers, and automotive electronics.
