A Varistor, or Voltage Dependent Resistor (VDR), is an electronic component which exhibits a predictable non-linear relationship between voltage and current. V240ZC05PX2855 is a Varistor. These devices are most commonly used in AC-DC switching power supplies, circuit protection, EMI/RFI filtering, and transient over-voltage protection.

The V240ZC05PX2855 is specifically designed for circuit protection. It works by limiting the voltage spike that can enter a circuit, and it features a low voltage clamping capability with Fast response time and low residual voltage. It offers high surge current capability and thermal stability.

The V240ZC05PX2855 has a 35 Volt breakdown voltage, a maximum clamping voltage of about 7V, and a maximum peak pulse current of 45A. It is constructed with a pressure-iron leaky core with a S20 zinc oxide ceramic shell and a copper electrodes. The Varistor is packaged in a TO-202-8 package with three leads.

The working principle of V240ZC05PX2855 is simple. It helps to protect circuits from over-voltage damage by clamping the voltage or by decreasing the resistance when a certain breakdown voltage is exceeded. The Varistor acts as a resistor under normal conditions but when the voltage gets too high, leads to a change in its resistance to help absorb the excess voltage. The device absorbs the excessive voltage, diverting it safely away from sensitive circuitry and providing effective over-voltage protection.

V240ZC05PX2855 is an ideal over-voltage protection solution for a wide range of applications, including line-powered consumer electronics, computer systems, telecommunications, automotive, industrial, and medical products. It can be used for a variety of purposes, such as surge protection, lightning protection, power supply surge protection, filtering of electrical noise, and clamping of voltage transients.

The Varistor is easy to install and use, and offers superior circuit protection in a compact package. It is a reliable, cost-effective solution for protecting circuits from over-voltage damage, and is perfect for applications that require fast response times and high surge currents.
