TVS - Varistors, MOVs are passive components which can be used for circuit protection. Such devices typically prevent a voltage surge from damaging components in a circuit. The V240ZS05PX2855 is an over-voltage protector that acts as a two-way valve for AC and DC power surges. It can be used in a variety of applications and is optimally designed to protect the components in a circuit from electrical transients.

The V240ZS05PX2855 uses a zinc oxide varistor and is available in 25V through 565V working voltage range. It provides excellent over-voltage protection worked with a wide varistor voltage range. It is also RoHS compliant and UL recognized.

In terms of application fields, V240ZS05PX2855 can be used in cell phone, computer, power device and other devices to protect the circuit. In particular, it is suitable for many AC power supply applications. For example, it can be used for EMI noise suppression, over-voltage protection, voltage compensation, and surge current protection. The V240ZS05PX2855 is a Metal-Oxide Varistor (MOV) device that is designed to protect against transient voltage surges without the need for other circuit components.

The working principle of the V240ZS05PX2855 is based on the principle of electrostatic induction. When an over-voltage occurs, the zinc oxide varistor acts as a bridge between the source voltage and the load. It works to the reduce the peak voltage and current magnitude through dielectric absorption caused by the electrostatic charge. As the input voltage rises, the varistor’s capacitance increases. This increases the resistance offered to the current. As the current increases, the varistor’s resistance decreases and the voltage is reduced. The device then discharges the current and reduces the voltage below the threshold and returns the circuit to the state that existed before the over-voltage event.

In conclusion, V240ZS05PX2855 is a zinc oxide varistor with excellent over-voltage protection. It is available in 25V through 565V working and is RoHS compliant and UL recognized, making it suitable for many AC power supply applications. The working principle is based on the principle of electrostatic induction and it provides protection against transient voltage surges without the need for other circuit components.
